Best Multimeters 2021

Buying a multimeter is a difficult task to take because there are so many multimeters out there, you wouldn’t know which would give to the best output. However, in this guide, we would be reviewing the best multimeters, if you need to acquire one, you should read through this guide.

WHAT IS A MULTIMETER?

The multimeter is an indispensable device for the measurement of electrical voltage, current, and resistance. It allows you to measure electrical current, voltage level, and continuity according to the operating mode.

The best home multimeter is the equipment that everyone needs for the detection of all electrical problems in your home.

How Well Do Multimeters Work?

A standard multimeter should give valid information about the condition of power sources in your home.

Because multimeters program designed to provide read voltage and current, resistance exposure to excessive power can damage the unit by burning up its parts. Also if plugged in the wrong power source, it can burn up as well.

Different multimeters can tolerate different power strengths. For instance, an HVAC multimeter can withstand more electrical exposure than a basic unit. If you are not sure of how much electrical current is passing through your home electrical lines, do not plug a multimeter into any of your power lines.

Considering painting your home? you need to get concrete paints and ceiling paints. You might also want to get paint rollers to make the painting a easier for you.

MULTIMETERS BUYER’S GUIDE

Accuracy

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 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. An extremely precise multimeter is only required for commercial purposes for those with specialized needs.

Safety Features

If you’re going to be tackling circuits with more than 30-35 V you should 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. 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.

Analogue or Digital

The biggest decision you’ll need to make is whether you want an analog or digital multimeter.

  • 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, though some electricians still prefer the old school clarity of an analog readout.

  • 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.

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.

Current

There are two types of electrical current that your multimeter should measure, AC and DC. While most of the multimeters available today will measure both of these, not all of them do.

  • AC

AC stands for alternating current, and it’s when the electricity is continuously flowing back and forth in both directions. This is the type of current that is present in the electricity powering your home, so electronics that plug-in will all utilize AC.

  • DC

DC is direct current that flows continuously in only one direction. You’ll find DC in all battery-powered electronics. Unlike multimeters, you don’t have to worry about the current when getting tools like drywall spackles and drawer slides.

Measurements

Most multimeters are going to measure the basic voltage, current, and resistance. These are measured in volts, amps, and ohms, respectively. When you start getting into the higher-end multimeters, you’re going to start seeing more options for what can be measured.

These can include temperature, continuity, capacitance, resistance, and frequency. While you may not need all of these functions, it could still be a good idea to prepare for the future by getting a multimeter with more options than you think you need right now. Unlike multimeters, lipo chargers do not measure current, but they charge lipo batteries.

Auto-range VS Manual-range Multimeters

Do you know the exact range of the current you’re testing? Often, the answer is no. In such cases, an auto-range multimeter can save you a lot of time and headache trying to determine the exact range to get a precise measurement.

With an auto-range meter, you’ll simply select the type of current you’d like to measure, and the device will give you the readout. If using a manual-range meter, you’ll have to go through each one of the individual denominations until you get the most accurate reading.

Unless you know exactly the range you’re looking for, most people will find it easier to use an auto-range multimeter. On top of this, the auto-range meters usually include a function that will allow you to measure manually, so there’s no advantage to skipping this feature.

Tacklife Digital Multimeter TRMS 6000

B07VNFVDW8

With an impressive feature list usually seen on multimeters many times more expensive, we had doubts about the Tacklife DM01M from the start. It lived up to our expectations. That said, you’d be hard-pressed to find more features stuffed into a lower-priced multimeter.

For starters, it has a non-contact voltage tester, a backlit LCD, and a built-in flashlight. It meets safety specifications for 600V CAT-IV and 1,000V CAT-III, which is pretty awesome at this price.

Unfortunately, we couldn’t get ours to give any sort of accurate reading. The main reason being that the leads just don’t connect to the inputs properly. They are too loose, experiencing far more play than is acceptable. This makes it pretty much unusable.

PROS CONS
Packed with features Leads are too loose when plugged in
CAT-IV 600V and CAT-III 1,000V Won’t give a proper reading
