Editor's Note: We updated our multimeter review on November 21, 2024, to include more recommendations in our award section.
We recommend the Crenova MS8233D for the majority of folks getting started with electrical projects, as well as DIYers and homeowners with enough knowledge to safely take on smaller projects without the need for a contractor. This capable multimeter is jam-packed with functionality at a price that won't break the bank. It can measure resistance, alternating and direct current, voltage, frequency, capacitance, and even live wires without probes. It has a continuity check and a diode test, allowing the current to run in one direction. This device also includes handy features like a backlight, hold, and max functions, and includes the typical point probes, a pair of alligator clip test leads, and a nice storage case to keep it protected in your tool bag when not in use.
Built with a range of people in mind, this meter does not offer some of the more advanced features, like a temperature probe or a dedicated transistor tester, which might be better suited for more advanced electronic hobbyists anyway. Also, it only has a maximum function and no minimum function. The compact Klein Tools MM400 is another well-performing multimeter, though not as friendly to the wallet. Still, the Crenova MS8233D is a great value and easy to use, so we think it more than compensates for its shortcomings, making it our top recommendation and also a great bargain.

The AstroAI 6000 earns its spot as a favorite multimeter for electronic hobbyists. Compared to other premium products, this model combines an impressive set of AC and DC measurement capabilities in a convenient and affordable package. This meter has plenty of additional functionality, allowing you to check components like transistors, diodes, resistors, and capacitors, along with measuring temperatures using the thermocouple, lending it toward benchtop work when piecing together prototypes on bread boards, or simply trying to determine the value of a resistor or type of transistor in your parts bin. The AstroAI 6000 is an excellent option for DIY electronic projects, household wiring repair, or working on 12/24 VDC systems found on cars and boats.
Though our testers really like the AstroAI 6000, it has some minor drawbacks. First, the magnetic hanger is not incredibly strong, so you might unintentionally knock it off if you are using it to adhere the meter to a magnetic object. Our tests also revealed the magnet tends to collect metal flakes, component leads, dirt, and other loose metallic objects. Unfolding the kickstand is a little tricky, and we found it hard to pull the probe covers off when you need longer ones. The AstroAI 6000 has a higher tolerance than some models, but this most likely won't matter much unless you are doing very high-end technical work. We also found the rather large size of the AstroAI to lend it best to benchtop work, as it is nearly twice the size of much more compact and nearly as capable multimeters. For beginners, the Neoteck NT8233D Pro is worth checking out. It is easy to use and has solid features and readings. Gripes aside, though, the AstroAI 6000 is an exceptional digital multimeter and a great tool for troubleshooting all sorts of circuits and wiring and is the multimeter we recommend first for hobbyists.
Taking temperatures with the probe included with the AstroAI 6000
If you only have the occasional electrical project and are shopping for a low-cost option to toss in your toolbox, check out the AstroAI AM33D. This simple multimeter can help with troubleshooting AC and DC circuits and has the crucial audible continuity check to help you track down a broken wire or loose connection. It includes a set of simple probes and has some of the basic convenience features we want in a multimeter, like an integrated backlight and a data hold function. It also features a square wave generator, though that's a feature most people likely won't use much.
The primary drawback we encountered during testing is this meter isn't auto-ranging. This can make it far more challenging for beginners to use — and it can even trip up some more advanced users if they aren't paying attention. We wish the backlight was a touch brighter and the integrated stand held the meter at a better viewing angle. Despite these flaws, this multimeter can get the job done at a fraction of the cost of the high-end models and is a good choice if you don't frequently need to use one of these tools. If you need to measure large AC currents, the Etekcity MSR-C600 is a great choice, though it doesn't measure DC currents.
The AM33D by AstroAI has a built-in square wave generator.
The Fluke 117 is a highly technical meter for highly technical work. Offering plenty of advanced features and functions, this DMM is designed with electricians in mind — especially when it comes to taking AC measurements. We love that it features an integrated non-contact AC probe and comes with a clear and intuitive interface. This true-RMS meter also has a low-impedance input that can automatically detect the type of voltage being measured and choose the appropriate range. Additionally, you can purchase a current probe separately if you need to measure anything above 10 amps.
The Fluke 117 offers a wide range of technical measurement functions, but it is geared more towards those working on home or commercial wiring rather than a hobbyist playing around with DC circuits. It also costs significantly more than an amateur might want to spend, and it lacks dedicated NPN/PNP transistor testing. If this sounds too fancy for your needs, check out the Etekcity MSR-R500 we tested for a bare-bones model that is more affordable. Though it's just a bit more specialized than many users' electrical projects require, the Fluke 117 is an excellent professional-grade multimeter.

A Word of Warning
Working with high voltages, currents, and electrical systems is inherently dangerous or even life-threatening. Using a multimeter is not a substitute for proper training and knowledge. If you are unsure or confused about what you are doing, then you most likely shouldn't be doing it, as you can put yourself in harm's way. If in doubt, or just over your head, please leave it to a licensed and insured professional.
How We Test Multimeters
We spent hours comparing and scoring these products side-by-side, completing several electrical projects on the workbench, on some tractors, and in the house, along the way. We checked the resistance, capacitance, and gain of a plethora of electrical components, as well as the voltage of just about every outlet and battery we could find. We specifically tested for AC voltage and DC current. We also investigated any additional probes that were included, like thermometers. Our testing gave us important insight (and some strong opinions) about the included probes and each meter's overall functionality and user-friendliness.
The overall score for each multimeter comes from testing across five key metrics:
DC Measurements (30% of overall score weighting)
AC Measurements (30% weighting)
Other Functions (15% weighting)
Ease of Use (15% weighting)
Included Probes (10% weighting)
We hands-on tested each multimeter to see which were the best of the bunch.

Analysis and Test Results
To determine which multimeters are the best in class, we tested them head-to-head to score and rank all of their different functions. We compared their electrical testing abilities, ease of use, and operation. We also included probes, as well as any other testing leads in our side-by-side analysis. Lastly, we divided electrical measurement capabilities into DC and AC voltage and current, as well as other functions for ease of understanding. While some features can fall into multiple test categories, we've left those features in their most commonly used category for clarity and fairness.
What's the Best Value?
If your budget is limited and you are doing your best to balance performance and cost, we highly recommend the Crenova MS8233D. This auto-ranging multimeter has most of the common measurement functions and a few extra functions and is very easy to use, all at a relatively affordable price. The AstroAI AM33D is another excellent option if you are shopping on the tightest of budgets, but the lack of auto-ranging makes it a bit more difficult to use. These less expensive multimeters will typically have a reduced set of measurement capabilities compared to the top-tier models. For example, the Crenova and the AstroAI AM33D can't directly measure the gain of an NPN or PNP transistor like the AstroAI 6000 can. Many cheaper multimeters also lack non-contact voltage detection, like the Fluke 117 and Crenova MS8233D are capable of. However, these budget meters typically cover all the basic measurements a typical DIYer or homeowner will likely ever need. You should think carefully about the projects you have in mind and make sure you aren't paying for an overly technical or complex meter that your electrical projects or home improvements may not require.
Most have large dials on the front that make them easier to adjust.

DC Measurements
This metric considers each device's Direct Current (DC) measurement abilities. Most electronics hobbyists get started with low-voltage DC circuits, given they are usually less dangerous and much more forgiving in nature than higher-voltage DC circuits. We rated and compared the DC voltage and current measuring abilities of each product and any other unique DC-specific features for each model.
The AstroAI 6000, Crenova MS8233D, Etekcity MSR-C600, Klein Tools MM400, Greenlee DM-45 600 Volt, and Fluke 117 all impressed us in this regard. When taking a DC voltage reading, all of these meters auto-range, making them a breeze to use. We found the Crenova and the Fluke 117 to be very accurate, having a listed tolerance for most ranges of plus/minus 0.5%.
Taking DC measurements is easy with most of our models, and extremely accurate with our top models.

However, when measuring current with the AstroAI 6000 and the Crenova, you'll need to set the correct range — something you don't need to do with the Fluke 117, which can automatically select the range for you.
While the Etekcity MSR-C60 is mainly useful for measuring large AC currents, you can still measure other things, like the voltage of an SLA battery.

Automatic or Manual Range?
An automatically ranging (aka, auto-ranging) multimeter can be much easier to use, especially for those just getting started with these products. This means that the meter will automatically pick the correct range for things like voltage measurements. You just set the dial to DC or AC voltage, and the meter will show the correct measurements. Manual or non-auto-ranging meters require you to set the correct scale for an accurate measurement. For example, you might have five different options when it comes to DC voltage measurements (0-200 millivolts, 0-2000 millivolts, 0-2 volts, 0-20 volts, 0-200 volts, and 0-500 volts). The meter will usually show a 1 or an overload symbol if you try and measure a voltage higher than the set range. The precision (number of decimal places) will also change depending on your scale, so you need to think about what you are measuring and try and select the smallest scale to get the most accurate measurement.
The AstroAI AM33D is rated to measure up to 500V with a Category II insulation rating. However, it isn't auto-ranging, so you need to set the appropriate scale for your measurement, choosing between 0-200mV, 0-2000mV, 0-20V, 0-200V, 0-500V, with the precision (number of decimal places) of each measurement changing for each range.
Also standing out in this metric with its series of common-sized built-in battery load testers is the Innova 3320. One of three LEDs will light up to let you know if the battery is charged, on the border, or depleted.
The Innova 3320 gives you a visual LED indicator for the amount of charge in a few common batteries.

AC Measurements
Next, we compared how these products did with Alternating Current (AC) circuits. We rated and scored things like the voltage and current measurement capabilities and any other AC-related features, like a non-contact voltage sensor or current measuring clamp.
A few products immediately stand out when measuring AC voltage and current: the Fluke 117, Etekcity MSR-C600, and the Crenova MS8233D. The Fluke 117 is an electrician's True-RMS multimeter, featuring a series of advanced AC measurement tools, like an auto-volt feature with a low-impedance input and a non-contact voltage sensor. It is auto-ranging for alternating current and voltage and can also measure frequency.
Taking AC readings is easy with the probes of the Crenova MS8233D, but the non-contact live wire detection feature can be used to add a small margin of safety to the task.

However, when measuring large alternating currents, both the Fluke 117 and Crenova MS8233D are outperformed by the Etekcity MSR-C600. While the Fluke and Crenova can only measure up to 10 amps of current without accessories, the Etekcity can measure up to 400 amps using its included non-contact current clamp. Even better, you don't need to break the circuit and wire the meter in series when using a non-contact clamp. This feature works best when you only measure a single, unshielded wire at a time. However, you can buy a current clamp separately for other products, like the aforementioned Fluke or the AstroAI 6000, if you want to measure higher currents with other products.
It is also worth noting that, like the Fluke 117, the AstroAI 6000 is a True-RMS meter. This means they can more accurately measure complex electrical waveforms, like those found in HVAC systems or variable motor drives — particularly brushless motors and their electronic speed controllers. Additionally, it is worth mentioning the Kaiweets KM100 doesn't have AC current capabilities, though it can measure AC voltage.
The non-contact VoltAlert sensor on the Fluke 117 is a quick and easy way to check if there is power, though it can sometimes be fooled by shielded conductors or other circumstances, so you should always double-check before working on the circuit.

Other Functions
While AC and DC measurement abilities are critical for any good multimeter, it is important not to disregard all of the other measuring capabilities these products have. All of the models we tested have a diode, resistance, and audible continuity check, with a few meters going even further. The AstroAI 6000 can also measure capacitance, transistor gain, duty cycle, and temperature using its K-type thermocouple.
The Neoteck NT8233D Pro, Fluke 117, and the Crenova MS8233D can also measure capacitance, but the Crenova adds a non-contact live wire detection feature that is excellent for homeowners who are trying to safely add a circuit for things like hanging a tv on a wall, and want to verify they've flipped the correct house breaker off before doing any potentially dangerous work on a live wire.

The AstroAI 6000 can be helpful with its NPN/PNP transistor gain functions if you are doing lots of circuits with surplus transistors. While this isn't the most useful, it can be handy for getting a rough idea of the DC gain when using surplus parts or other semiconductors, when you can not easily locate a datasheet. We did find the universal socket/adapter for these extra functions on the AstroAI 6000 to be a bit finicky, and see potential that we could accidentally lose it at some point.

While this isn't necessarily a measurement function, both the AstroAI AM33D and the Etekcity MSR-R500 have a dedicated square wave output, which is useful for testing amplifier circuits. These also have a diode check, which is handy if you are working with LEDs.

The Klein Tools MM400 has continuity and resistance under the same setting. It defaults to continuity, so you'll need to remember to press the select button until you see the resistance icon show up. In addition to measuring capacitance, frequency, and duty cycle, this model includes a thermocouple probe that is rated at 1000° F.

Ease of Use
After the electrical measurement tests, we rated and scored how easy it was to use each device. We considered how simple or challenging it was to set the range, if the device comes with a “Max,” "Min," or “Hold” option, whether or not there is a backlight, the quality of the kickstand, and the overall user interface.
Size matters when you are doing work on the go, but matters less if you plan to have a multimeter permanently living on your test bench. We found the smaller multimeters were more convenient to handle in work environments, and then toss back into a toolbox or truck. Its small size, wide range of features, and no-contact live wire detection, made the Crenova MS8233D our favorite all-around, while the AstroAI 6000 earned a special spot on our electronics test bench, where its overall large size didn't impact ease of use, and we were able to take advantage of its multifunctional socket to test capacitors and transistors used in projects.
Three very different sizes of multimeters.

“Hold,” “Min,” and “Max” functions are also quite handy when diagnosing circuits, something the Fluke 117, Klein Tools MM400, Greenlee DM-45, and the AstroAI 6000 all have. Except for the Innova 3320 and the Etekcity MSR-C600, most of the tested products also have a backlight.
While it's not recommended to work on electrical projects without proper lighting, the integrated backlight can make it easier if you absolutely have to.

While most of these devices include a kickstand, the AstroAI 6000 also has a handy magnetic hanging strap. The Fluke 117 has this too, but it is sold separately. However, we do like the integrated probe holders on the Fluke 117, which keeps the test leads nice and organized.

In addition to a wide range of features, including new capacitance features added to this updated model, the Crenova MS8233D also makes finding a live wire a breeze, and does it with a comfortable margin of safety due to its NCV, or non-contact voltage detection. However, it's worth mentioning again that working with high voltage and amperage circuits is inherently dangerous, and the NCV is not a substitute for proper knowledge, skills, or safety precautions — rather a helpful hand in addition to those skills and knowledge.
The Klein Tools MM400 features one of our favorite kickstands. The stand props the device up at a great viewing angle, and it stays in place, even when shaken or bumped. The hard rubberized bottom grips the surface on which it is placed so that it won't slide around. If you like the idea of being able to hang your multimeter, the Greenlee DM-45 has an integrated hook.

Included Probes
Finally, we assessed the quality of the included probes. Since you can always get higher-quality probes separately, it doesn't make a huge difference. However, there are a few standouts that are worth mentioning.
We like the safety covers included with some probes, such as the ones on the Fluke 117, Klein Tools MM400, Greenlee DM-45, and the Neoteck NT8233D Pro. These let you change the amount of conductive surface exposed to match the application. We also appreciate that the Neoteck NT8233D Pro and the Crenova MS8233D include the typical point probes and a pair of alligator clip probes.
You can remove the insulating cover to expose more of the probe if necessary.
Checking the value of an electrolytic capacitor with the Neoteck's included alligator clip probes is a breeze.
Some multimeters come with probes that are higher quality than others.
The clip probes can be exceptionally convenient for measuring components or other circuits and give you a reliable way to get a good connection without holding the probes in position. This frees up your hands and reduces the likelihood of an intermittent connection.
We conducted hands-on testing of all of these multimeters in order to determine the best.

How to Pick a Multimeter
We've put together four key buying considerations, including features, budget, and ease of use, to help simplify your decision.
What is the Complexity of Your Electrical Projects?
From DIYers to commerical sized electrical projects, multimeters are an essential tool to help measure electrical components. For someone starting out with a multimeter, certain functions, such as the use of an auto range finder, will drastically help with the ease of use. Determining the depth of your projects and the amount of use you plan to get out of your multimeter will help steer you in the right direction both from a function and price standpoint.
Choosing the right multimeter starts with considering the type of projects you plan on tackling.
Credit: Abriah Wofford
What Features are Important?
Multimeters come equipped with an array of features that can often feel overwhelming to first-time buyers. For first-time users and hobbyists, cheaper options with fewer features and easy-to-read displays are often easier to use and can tackle smaller tasks, such as checking continuity on cords or batteries. If you have specific tasks in mind, such as working on HVAC or generators, features such as temperature or frequency are important. Consider the type of electrical projects you have in mind and your relative experience with multimeters as a way to gauge what features may be helpful or not.
How Much Voltage are You Working With?
Checking the CAT category of your multimeter is a reliable way to ensure your meter is capable of safely operating within a given electrical system. For most at-home users, a CAT II level, such as testing an outlet, is appropriate. For higher voltage work, cat III and IV multimeters are capable of testing industrial-level equipment and projects such as larger lighting systems. Spending some time getting familiar with voltage levels and the appropriate CAT rating is an important process for finding an adequate multimeter.
Is Durablity a Concern?
Depending on the type of use and frequency of use, finding a multimeter built to last is important. Some meters can handle rougher use, like those with an outer rubber casing that adds an extra layer of protection against drops and falls. If you plan on using your multimeter on the job site or just want a multimeter that is built to last, consider options that will hold up to extended use.
Ultimately, the right multimeter comes down to your project goals and intended use.
Credit: Abriah Wofford
Conclusion
Our review includes the information and details you need to narrow down the options to the perfect multimeter for your needs and budget. Remember, working on electrical circuits and systems can be extremely dangerous and should only be done if you have the proper knowledge and training. With that in mind, stay safe, and best of luck on your next DIY project.
