Top 5 Best Multimeter Under 100 Reviews

Any electrician – or aspiring electrician – needs a multimeter in his arsenal. They are necessary for any type of electrical work, be it adjusting a wall outlet or fixing an electric appliance. When it comes to choices, the market is full of multimeters. But if you don’t want to spend a fortune, perhaps you’re wondering which is the best multimeter under 100.

Here's a list of Top 5 Best Multimeter Under 100

After all, while heavy-duty professional tools are often much more expensive, there are also many cheaper multimeters that live up to the expectations and don’t require you to rob a bank to buy it.

If you’d like to know which are some of the most reliable models, check out our top picks below.

What to Look for When Buying a Multimeter

It’s hard to get the best multimeter on the market unless you know what to look for before buying. Here are a few features you should consider before making up your mind.

Multimeter Type

There are basically two types of multimeters, digital and analog. The digital ones are slowly taking over the market, but this doesn’t mean they are always the best choice.

  • Digital multimeters: Display readings on an LCD screen, are typically more reliable and have more impedance than analog units. However, the sensitive electronic components are prone to break. They are also slower in providing readings than analog multimeters.
  • Analog multimeters: Consist of a dial with a needle that indicates the measurement value. Due to a slight swing of the needle, it’s sometimes hard to get 100% accurate measurements. However, these units provide reading values faster than digital ones and last longer. They are also precise, and professionals still prefer analog multimeters over the digital ones.


Another thing you should check is the type of measurements your multimeter returns. Even the most basic models can usually handle the following three types:

  • Voltage: Is used to measure the electric potential difference between the components of an electric system, and usually vary from 200 millivolts to 600 volts.
  • Ohms: Measure the resistance of electricity. The higher the value, the higher the resistance of the wire.
  • AC: Measures the amperage of the alternating current from 200 milliamps to 600 amps.

Besides these measurements, the most advanced units also measure other variables including capacitance, pressure, frequency, and temperature.


Regardless of the unit you want to buy, don’t forget to check its design too. Some multimeters have large designs and are cumbersome to carry. Others fit in the palm of your hand, and consequently inside a pocket, and are easy to take around with you.

If you’re going for a digital model, check the size of the screen and of the digits displayed on it. A backlit screen is a must if you want to be able to read the measurements in low light or no light conditions too.

Also, check the average lifetime of the batteries that go with your unit. Most multimeters use standard AA or AAA batteries, and a set can go a long time if you invest in a unit with auto-shutoff function.

With this in mind, let’s now have a look at the best multimeters under 100 in 2019.
