What to Look for in a Multimeter Under 100$

Knowing which multimeter has the best features is only the first step. Next, you need to look at some factors to get the device that best suits your needs.

Accuracy- How Accurate Is it?

Frankly, an inaccurate multimeter wouldn’t appeal to most of us. But, on the other hand, faulty results can be hazardous, so you need to ensure you pick a multimeter as accurately as possible.

For that reason, it would be best if you consider multimeters with True RMS scales. These usually make more accurate readings for any test you make.

Ease of Use

No matter how useful a tool is, it all boils down to one thing: ease of use. The device should be easy to use. The ease of use will usually be dictated by features such as auto-ranging or auto shut-off options. The display also plays a significant role in whether a multimeter is easy to use or not.

Therefore, when selecting a multimeter, ensure you pick one that will give you as little trouble as possible using it. Fortunately, most multimeters aren’t usually that hard to use.


The ideal multimeter should be able to test various standard tests. What you don’t need is a multimeter that can only test a specific number of tests. Find more about the difference between DMM and DVOM multimeters.

Such a multimeter would limit your ability to use it. It might even lead to you getting another multimeter. Most of the multimeters here on our list can test very many functions, making them quite versatile. It would be best if you went for such multimeters to avoid any disappointments.

How Is the Display

The display is where you will see the readings for every test. That’s why you have to choose a multimeter that has a large display to ensure you don’t strain to see the readings.

It is even much better if the display is backlit since it means you won’t struggle to do readings even in dimly lit environments.

How Safe Is it?

Safety should be the number one consideration for any tool you buy—that isn’t any different for multimeters. A safe multimeter will prevent you from having to worry about any electric shocks as you use it. It would help if you thus went for one with some safety features to avoid any unavoidable accidents.

Is it a Rugged Device?

While we accept that no tool can have an unlimited lifespan, it shouldn’t be the type to sustain damage that easily. That is why you will need to choose a rugged multimeter. A rugged multimeter will withstand demanding work environments and survive drops.

FAQs: 4 Questions & Answers

Are cheap multimeters any good?

Yes, they are. There are several good deals on multimeters you can get on the market right. Not every good thing needs to be expensive.

How much is a cheap multimeter?

You can get a multimeter for as low as you can afford. However, to get the best deal on a cheap multimeter, you must consider those in the 40$ to 100$ range. Such devices will be affordable but won’t sacrifice performance.

Can a multimeter kill you?

While multimeters can be quite hazardous, they wouldn’t kill a person if you handle them disorderly. Only in extreme cases where the shock from the device you are testing is way too much can a multimeter cause considerable harm to a person.

But if you use the multimeter properly, then there will be no cause for worry.

How do I know if my multimeter is bad?

There are several things to look out for in a faulty multimeter. The most glaring one will be hugely inconsistent or false results. This one usually sticks out like a sore thumb. For example, if your multimeter has a light indicator but can’t see it working anymore, that could also point to it being faulty.


If you were at a crossroads over which multimeter to choose while operating on a shoestring budget, we hope we have helped you solve that issue.

Added features will come in handy for you when you are selecting a multimeter. Such features include auto-ranging capability, automatic shutoff, or even the ability to measure temperature in addition to the other tests.
