Award: Best Cheap Multimeter
This is a handy little multimeter that is a great addition to any garage and toolset. This is the best cheap multimeter money can buy. We don’t necessarily like to call decent products cheap, but the Innova 3320 certainly could be classified as such. Nevertheless, if you only plan to use the multimeter occasionally buying the best cheap multimeter is a wise course of action.
A clear display, accurate readings, and a fairly sturdy built quality make this the best multimeter under $20. Four corner guards protect the unit itself, so when you drop it or toss it in frustration (just kidding) it will hold up just fine and be protected. This meter is powered by 2 double A batteries and has an auto-off feature to help save battery juice.
Award: Best Multimeter for the Money
The best multimeter for the money is the Mastech MS8268 multimeter. The latest multimeter product from the trusted brand Mastech. Honestly, most of the Mastech multimeters are great products. This new release is the best multimeter for the money.
It is basically a multitester too. It comes with a 1-year warranty. Auto powers off, blue LED black lit LCD display, auto-ranging with relative measurement, AC/DC 1000 V, diode checker, and more. For $25, you can see why it won our award for the best multimeter for the money.
Better accuracy and safer testing are what Tacklife boasts with this multimeter unit. What do we like? The flashlight feature, which makes it easy to work with only two hands in dark places.
It’ also has a temperature measurement, which increases safety tenfold. The DC Voltage measures up to 1000Volts, and the AC up to 750V. Tacklife will help you get your job done.
Our next option is a little different than the rest of our choices on the best multimeters reviews. The auto-ranging clamp multimeter makes it easy to test AC current just by opening the clamp.
This small unit packs a big punch of data, by being able to hold information, let you know when you’ve hit a max reading point, and going into sleep mode automatically to save batteries.
Award: Best Multimeter for Electronic Basics
The Klein MM500 Multimeter is another great option with high ratings and at a reasonable price. This is great for basic tasks such as doing repairs on electric ranges, outlets, switches, breakers, refrigerators, etc. Furthermore, if you are poking around your vehicle, trailer, or RV this would be a great unit for you.
The Klein isn’t the cheapest of the cheap, but it isn’t going to break after 1-2 years either. It is a great mid-range multimeter with plenty of drop protection.
It is auto-ranging, dust and waterproof, and can handle up to 10-foot drops. The safety rating for this unit is a CAT IV for up to 600V. This wins our award for the best multimeter for electronic basics.
The Extech EX330 is at the opposite end of the price spectrum than that of the Fluke 87-V Digital Multimeter. This is the best budget multimeter for around 50 bucks. You’ll be hard-pressed to find a multimeter unit that is better than the EX330 at the $50 price point.
It is definitely the best cheap multimeter out there right now. This unit has a wide array of features. You can test current, capacitance, frequency, continuity, diode, duty cycle, resistance, and voltage.
On top of all that you get auto-ranging, continuity tester, tilt stand, and the data readout can be set to max hold/data hold/relative. For $50, that is pretty dang good.
The fact that it has the capability to sense temperature makes it worth this price alone. This unit runs on 2 triple A batteries. Even though this model may be aimed at the professional market even hobbyists can afford it.
If you keep scrolling, you might notice a brand trend called Fluke. What can be said? They are one of the best measurement and diagnostic tool manufacturers out there.
They make high quality stuff, and the Fluke 117 HVAC multimeter is no exception. That is why the Fuke 117 won our award for the best HVAC multimeter.
HVAC pros (heating, ventilating, and air conditioning) need specialized multimeters like the Fluke 117. For example, Fluke 117’s built-in thermometer and microamps feature is great for HVAC applications.
To keep costs down on this device, Fluke removed the high amperage selection from this model. This is probably okay since most HVAC applications do not call for averages that go over 1 Amp.
Award: Overall Best Multimeter for Professionals
If you’re looking for the best digital multimeter regardless of cost, the Fluke 87-V is a great choice. This is a clear favorite among the online community and seasoned technicians alike.
Fluke is the leading brand in the multimeter category. All of their products are well polished and provide accurate readings. Of course, these products are matched with whopping price tags because of their high quality. But if you want the best multimeter, this is the one.
An analog bar readout provides the best of both digital and analog worlds. The auto-ranging system is on point but can be switched off if you want to change to manual.
Arguably the best feature of this multimeter is that it will beep at you if you put the wrong thing into the input jack. That makes this unit great for inexperienced technicians and will prevent them from taking the wrong measurement.
Another awesome feature is that this puppy can measure up to 20A for 30 seconds at a time. Sure, it is one of the most expensive models money can buy, but you’re getting arguable the best digital multimeter out there.
Award: Best Automotive Multimeter
If you’re looking for the best automotive multimeter, you can’t beat the Fluke 88V. This easily won our award for the best multimeter for automotive applications.
The Fluke 88V is excellent for measuring signal pulse width and determining the health of an injector. If you are a mechanic or have a little auto experience you’ll know these pesky injectors require regular attention.
The Fluke 88V has some sweet stats: 1000V AC and DC, maximum resistance of 50 M, and withstands even the most hazardous of spikes up to 8,000 volts. This unit also has the capability to carry out diode tests on vehicles.
It is extremely accurate at +/1 1.00 percent. The maximum conductance that it will measure is 60.00 nS. Fluke backs this bad boy with a lifetime warranty. How’s that for peace of mind?
What is a Multimeter?
A multimeter is a test tool instrument that measures two or more electrical values such as voltage (volts), current (amps), and resistance (ohms). There are the top main types of multimeters: analog and digital.
Analog multimeters incorporate a microammeter that has a moving pointer that displays readings. A digital multimeter is known as a DMM. Digital multimeters have a numeric display and may other visual cues that help represent the measurement readings.
Multimeters are standard diagnostic tools for all technicians in the electrical and electronic fields. In fact, without a multimeter there isn’t much an electrician can do safely. If you are looking for more information about how to use a multimeter you can stop by the tutorial at sparkfun.com “how do I use a multimeter“.
While we cover the very basics in this section you may wish to learn more about electricity, circuits, breadboards, and etc. Such topics are beyond the scope of this page. The main focus of this review is to provide readers with an overview of the best multimeters.
What Multimeters are Capable Of
Multimeters make quick work of finding faults in a circuit. They are generally handheld, very portable devices.
Some cheap multimeters are sold for as little as $10-20 and work for many of the most basic applications. These really cheap multimeters are built with lower quality and if you accidentally forget where you placed it and step on it you can kiss that unit goodbye. Cheaper models occasionally give inaccurate readings but a few are actually pretty decent, which we’ve included in our reviews section.
Another category of multimeters is referred to as bench multimeters. These are for more serious applications where extremely accurate measurements and diagnostics are required.
What to Consider Before Buying a Multimeter
Here are the top features to consider before taking the plunge and buying a multimeter. A great deal of what decides which multimeter is best for you is what you plan on using it for.
As long as you have one with the right features it will make your work easier, safer, and more efficient. Other than cost, here are a few other things you should think about before hitting that buy button.
Analog or Digital
The biggest decision you’ll need to make is whether you want an analog or digital multimeter.
The Deal with Digital Multimeters
Some people prefer analog over digital because they like the readouts better and consider them more visible. They will argue analog makes it easier to see changing trends than with a digital multimeter.
Much like a speedometer on a car, digital speedometers make acceleration difficult to judge because the number readout will be jumping all over the place (especially with a very fast car that can accelerate quickly).
The same relationship applies when it comes to multimeters and electronics. The best digital multimeters have excellent visual readouts such as bar graphs. By and far digital multimeters are more popular than analog at this point in time, though some electricians still prefer the old school clarity of an analog readout.
Nevertheless, analog meters have their own issues too.
A Closer Look at Analog Multimeters
Analog multimeters are known for having lower input impedance than digital multimeters. This impedance is responsible for indicating the sensitivity of the current that is being measured.
The higher the input impedance, the better the meter can measure any type of voltage. Another issue with analog meters is that they are usually limited to reading amps, volts, and ohms.
That is the main benefit of getting a fancy digital multimeter, they go far beyond just these three measurements. The utility of these modern devices can be pretty handy if you are working on multiple electronics at the same time and need to efficient.
Ultimately, analog multimeters are getting harder to find because of their lack of features and the shift to digital.
Auto Ranging or Manual Ranging
Auto-ranging means that the multimeter has the ability to recognize what you are testing. You do not have to input your range. Simply let the device do the work and output the desired measurement.
That saves you the hassle of having to know all those resistance, capacitance, voltage, and all those other values. The multimeter will find the value for you whereas if you had a manual ranging multimeter there are preset ranges and you have to know which range of values your component falls under to get a reading at all.
Of course, in a perfect world, every multimeter would give 100% accurate readings. However, that is far from the case. Whether imperfect manufacturer processes, cheap components, or user error, there’s a lot that can possibly go wrong.
Honestly, if you are working on a professional basis, you are going to want to spend more money to ensure you are getting a product that is going to read accurately.
DIYers and electronic hobbyists probably won’t care about accuracy as much but you still want one that gives you a good ballpark number. Clearly a multimeter that is extremely precise is only required for commercial purposes for those with specialized needs.
If you’re going to be tackling circuits with more than 30-35 V you should really consider getting a multimeter with safety in mind. Check out the measurement category rating as well as how the multimeter is designed. Internal blast shields, shrouded banana plugs on the probes, wide flanges to prevent slippages, isolation slots that prevent arc over, and sufficient input protection is a handful of the things you should be checking on design-wise.
Basically checking those boxes and spending a bit more money on a model that has those features is always worth avoiding a major accident! If you overload the multimeter, you don’t want the thing blowing up in your face.
Design & Build
Not on the top of everyone’s list, but if you work in a construction typesetting you probably want something that is bright orange or yellow. This will help prevent accidents or someone crushing your new device. High-quality multimeters will usually have a more durable casing and finish.
The brand is a big factor for a lot of folks when they are considering a new tool, as they may have had good or bad experiences with certain brands in the past. Some of these even have bumper corners for extra protection. The probes within typically are insulated with silicon instead of the cheap PVC found in lower-cost models.
