The Best Digital Multimeter Reviews

Best Digital Multimeter

Any electrician worth their salt know how vital a multimeter is. While analogs are a classic, the precision, accuracy, convenience of digital multimeters are on a whole other level. There are plenty of these tools out there, but if you’re not sure about what to get, you won’t get the results you want.

Don’t worry. With our review and guide, you’ll find the best digital multimeter for your work. There are plenty of great models that specialize in one feature or another. Some are just great value-for-money deals others have a better user interface, and so on.

Now then, let’s get our cords and outlets ready and dive into the guide!

Why You Should Buy This?

There are many people around who’ve heard that they need a multimeter but don’t know why they’re so important. So, we’re going to take a moment to explain.

Mandatory for All Electrical Work

In simplest terms, multimeters are a measurement tool that helps a user measure voltage, resistance, and current.

Whether you’re experimenting with robotics or just replacing a fan, you’ll need to have accurate voltage measurements. Random estimations of voltage and current could have extremely dangerous repercussions. That’s why multimeters are an essential tool for pretty much every electrical job.

Diagnostics Tests

Let’s look at an example. Imagine your TV stopped working. It’s not turning on anymore, but there’s no indication that the TV itself is damaged. So, you check its outlet. You use the multimeter to check if it’s dishing out the necessary voltage to turn the TV on. If it’s not, then you figure out what to fix.

Yes, one of the main uses of a multimeter is diagnostics. They help technicians figure out what is lacking in your electrical devices and outlets.

Specialized Tests

Also, some of them have bonus features. These help technicians with specialized tasks that they can’t get out of through their basic use. That’s why a multimeter targeted towards a simple tinkerer is different from one meant for a professional technician.

In essence, if you have any plans on working with electrical equipment, you must have a multimeter. They’re the best way you can diagnose electrical issues and perform vital experiments.

Features to Look for Before Buying?

We’ve gone over 5 of the top models. However, you might still be unsure of what to get. For that, you’ll need to do some vital reading. We’re going to go over everything you need to know to find the best multimeter for your job.

Notice the Range

Multimeters are very different based on their voltage range. You shouldn’t work outside this range as it might cause damage to the multimeter and yourself. Generally, you’ll want to have something with up to 600 Voltage range.

However, that might not suit your needs. Only you can know what kind of voltage range you need for your work. So, always check out the ranges of a multimeter before you choose to buy.

Accuracy

Digital multimeters are hardly wrong. They’re meant to provide the most accurate numbers possible. However, there are many situations where there might be certain conditions that can throw off your answers.

If you work in an environment where ghost voltages are a common occurrence, you need a multimeter to handle that.

You’ll want to get something that has true RMS readings. These counter conditions that can throw off the measurements and provides the most accurate results. If your work involves high bandwidths or ghost voltages frequently, you’ll have to take these means to combat it.

Continuity Response Time

Response time is vital for any technician. If you need to make a lot of measurements, slow response time can be excruciating. The slower speed will make you less efficient, slower, and bored.

On the other hand, fast response times make your job much easier, bearable, and efficient. If you need to deal with a ton of measurements in short periods, you should examine the continuity response time.

Battery Life

Like the previous point, this is essential for professionals. Time is money, and you don’t want to waste it buying new batteries and replacing old ones. You should just buy one and have it last you a substantial amount of time before you worry about changing.

That’s what makes battery life so essential to any commercial user. Always use running time as a measurement for battery life. The longer it lasts, the better it is.

Display Count

Multimeters aren’t calculators. They don’t need to display millions or billions. Usually, 0 to 39,999 is good enough. However, not all multimeters can display that. It all depends on the minimum and maximum count of the multimeter in question.

In simple terms, the higher the count, the more numbers it can display. For example, a 4000-count display will return values from 0 to 39,999. On the other hand, if it had a lower display count, such as 2,000, it can return values from 0 to 19,999.

Of course, you’ll generally want higher display counts if you have the money. If your work doesn’t call for it and you’re looking for the best budget multimeter, you don’t have to worry about this much. However, if you’re working with a wider range of electronics, a higher display count is necessary.

Additional Measurement

Yes, a traditional digital multimeter aptly measures voltage. However, these multimeters can do a lot more now. Whether it’s the measurement of temperature, or anything else, a proper multimeter should allow you to do so.

Like we’ve mentioned before, temperature measurement is an important measuring tool for tons of thermocouple monitoring.

Measuring currents and resistance is important as well. Which forms of measurement tools you take depend upon the kind you need. Get an idea of the ones you do and make sure that they are present in each unit you consider.

Safety Features

Working with multimeters means that you’ll be dealing with electricity a lot. We all know just how dangerous electricity can be if things go wrong. So, we should always strive for a tool that can keep us safe while we use it. Rubber encasings are a great example of this.

Rubber nullifies electric shocks, so it keeps you relatively safer than when working without one. Not only that, they can keep your tool safe, in case you might drop it.

There are other features for safety as well. Multimeters can have cables that prevent explosions and prevent tearing. All of these are vital for a safe work environment, so make sure you always pay attention to what you’re getting.

Other Features

Trust us when we say there are practically countless additional features that make a multimeter unique. There are a ton of unique features in every model that is worth taking a look at.

It can be small features such as a handy built-in flashlight or a pop-up stand to make sure that you can keep using the tool without having to hold it up all the time.

One extremely handy feature is the no-contact measurement that allows you to take measurements without fiddling with cables and such. Backlighting is also another must-have as it allows you to see all numbers clearly and immediately. All of these make your job significantly easier.

Frequently Asked Questions

  1. Are these rechargeable, or do they need batteries?

Most need AAA batteries, but there are some rechargeable models out there.

  1. Should I get analog models instead?

Analog models severely lack the accuracy and features of a digital multimeter. You should try sticking to a digital model instead.

  1. How long do they last?

Battery life wise, it depends on the battery and the particular model. For the models itself, you should strive for a model that lasts for at least 3 years.

  1. Can I work without getting a multimeter?

Almost all electrical work requires a multimeter. So, if that’s what you’re doing, you must get one of these.

  1. Can they be dangerous?

If you have a defective unit or use them improperly, they can be somewhat dangerous. Of course, most developers take a lot of safety measures to ensure they are as safe as possible.
