Multimeters are, by their very definition, conglomerates of various devices, all measuring one thing or another, so finding the best digital multimeter is like trying to find the best holiday destination without knowing who is going to go.
So, when we started to look on the market for the best digital multimeter we actually started to look for the various types of professionals and amateurs that would need to use such a device. Ultimately we found 5 different categories of users and only after we had established what their needs were, we came up with the following list of choices.
Best Digital Multimeter of 2021
The essential thing to note here is that we came up with 5 choices and they all represent the best, but for different people. So, unless you are sure of exactly what range of products you need, make sure to scroll past the following list to the in-depth reviews we have created for each product.
There we have highlighted not only the most important features of each product but also what type of user each product is meant for.
Fluke 87-V Digital Multimeter
If there ever was a digital multimeter that could be considered “the best”, that would be the Fluke 87-V. To start with the obvious, it was designed and manufactured by Fluke, and they are the very best in the business.
Not only that, but they have created the 87-V to be their finest achievement and you can tell immediately as you pick it up can start to appreciate the craftsmanship that went into making it. Furthermore the technical specifications are quite impressive: it can measure up to 20 Amps of power and monitor them for 30 seconds.
It can create an analog graph for fast changing or unstable frequencies, making it a superior product even to the analog multimeters, which for years have been considered superior on this front. It has a dual display resolution, from 6,000 to 20,000 so you can monitor even the most minute changes in your readings.
It has both a CAT III 1000V and a CAT IV 600V safety rating meaning it can withstand surges of up to 8,000V. And it comes with a separate thermometer that communicates with the devices. Finally, it was designed and built in the USA which allows Fluke to offer a life time warranty with each device.
The only question that you have to ask yourself is whether you need to spend so much money on this device. We actually would only recommend this device to advanced electrician professionals who will be able to make use of its many features.
Fluke 115 Compact
Our second choice in the search for the best digital multimeter focuses on electricians, auto specialists and even student electricians who have already developed a passion for the field.
It is still a little bit on the expensive side, but when it comes to multimeters, you really can judge the quality by the price. The Fluke 115 Compact has an auto-range feature, and can measure up to 20 Amps, although it will only be able to monitor for more than 30 seconds loads that exceed 10 Amps.
That makes it an ideal tool for most specialists and being a Fluke product, you also have the certainty that you are using a truly accurate instrument. Its large LED screen is second to none we have ever tested, and it is easily read even in bright sunlight conditions.
The Mastech MS8229 is the perfect choice for that Jack-Of-All-Trades friend that you know, and if you do not know one, you are probably it. This multimeter has just enough accuracy and range to allow you to test your average laptop or smartphone charger, check if you can still bring back to life that computer that someone spilled juice on, or test whether your friend’s car battery can go through another winter.
Furthermore, the Mastech MS8229 is a 5 in 1 device that will allow you to check humidity, sound level, temperature, Lux, and DMM, making it an even more versatile tool than your average multimeter.
Its only drawback is that it does not really have the accuracy of the Fluke products we have featured so far, so an advanced electrician will find very little use from it.
Maybe you have a child, or the child of a friend, or even a grownup friend who has gotten tired of having to take their electrical devices to a specialist and is trying to fix things for himself around the house.
Maybe you are just that one person, and you know that there is a good chance you will one day soon return to using the services of a professional electrician but you would like to have a go at this yourself.
In that case, you will not want to spend a lot of money and you are not really in a position to need an extremely accurate multimeter, just something that will give you an idea of what is wrong and what type of capacitors you will need. In that case, the best choice for you is the INNOVA 3320 auto-ranging digital multimeter.
Triplett 1101-B Compact Digital Multimeter
Our final choice was also the most difficult because the Triplett 1101-B is the best digital multimeter for that struggling electrician who is just now entering the market and needs an accurate device but cannot afford a Fluke.
The Triplett 1101-B Compact Digital Multimeter is about as accurate as Mastech we have already talked about, but because it does not have all the other features, it is somewhat cheaper. It does share some of the features of a professional multimeter though, like a 10 amps range and the ability to change from auto range to manual range.
The LCD is backlit so you will be able to use it even in bright daylight conditions and it has a 600V safety rating. It may not be the best tool for a professional electrician but it will get you to a place where you will be able to buy and make full use of even the Fluke 87-V.
