What is the Best Multimeter for DIYers and Pros

But with this incredible ability comes a great deal of complexity—many new multimeter purchasers feel overwhelmed with the number of options available and all the different features out there.
As mentioned, the multimeter is capable of measuring such units as voltage, resistance, and current (basic units) as well as temperature, capacitance, and frequency (advanced units). Multimeters feature two wire probes—one red and one black—to measure positive and negative readings, respectively. Some units also feature accessory capabilities, making them even more versatile.
A multimeter is a pretty sophisticated tool, but we hope you’re no longer feeling overwhelmed or intimidated. With the insight you’ve gleaned from this article, you should have the knowledge and confidence needed to make the best multimeter purchase for you and your needs!
In addition to these, advanced multimeters can usually measure:

What is a Multimeter?

This refers to which type of screen and display method the multimeter uses.
As long as the manufacturer has tested the device for safety—and as long as you use the device properly and with care—multimeters are generally safe to use.
The average multimeter comes with two wires (red/positive and black/negative) for taking readings. However, there are also some more advanced units that include additional accessories such as alligator clips, a magnetic case, or additional probes/sensors.

If you only need the device for occasional use or small projects, you can opt for a basic multimeter to save some money. But if you’re an electrician, you’ll want to splurge a little and get a more advanced model.

How to Choose One

Simply put, the best multimeter is the one that best meets your needs. This means that it:

Type

Multimeters are complex devices, and as such, there are a few things you’ll need to consider before shopping around. To give you a head start, we’ve outlined the most important factors below.  

• Category
• Design
• Analog vs. Digital
• Basic vs. Advanced

Intended Use

 
Cons
The main difference between basic and advanced multimeters is in which units they’re capable of measuring.

What it Measures

You can tell right away that this analog multimeter from Tekpower is ready for some serious business. It may look old-school, but underneath its more traditional housing you’ll find a range of practical—and modern—features (take, for example, its backlit display and built-in stand). As far as measurements go, this multimeter can handle a number of units and its transistor tester can gauge both PNP and NPN. You’ll also appreciate its simple operation (you just need to utilize a large knob and a couple of buttons) as well as its 1-year warranty. If you’re looking for an analog-style multimeter that incorporates plenty of modern features, you’ve just found it!

• volts.
• current.
• resistance.

This is the multimeter that has it all, from True-RMS to a simple yet hardy design—not to mention its CAT III and CAT IV ratings!

• temperature.
• capacitance.
• frequency.

Accuracy

Multimeters are broadly classified into four categories, based on the unit’s intended use:

Whichever category you fall into, there are certain factors you’ll need to keep in mind before making your multimeter purchase…

Different Types of Multimeters

Pros

Category (CAT)

Will you be using it every day for professional measurement tasks, or will you be using it for the occasional around-the-house electrical fix? What types of measurements will you be taking most often?

• CAT I tools are used for electronic devices and equipment.
• CAT II tools are used for single-phase AC loads (such as those of appliances).
• CAT III tools are used for three-phrase distribution (like that of distribution circuits).
• CAT IV tools are used for the main supply source (such as electrical meters).

Old-school charm and convenient modernity wed in this multimeter from Tekpower; you can look forward to analog-style readings as well as a backlit screen and streamlined design.

Design

This multimeter from AstroAI is super-affordable, ideal for beginners or DIYers, and doesn’t skimp on features—a great choice if you’re on a tight budget.

• Fluke multimeters are perhaps the most popular. This type is used for calibration purposes, and basic models measure voltage and resistance.
• Autoranging multimeters are ideal for beginners, amateurs, and those who have never owned a multimeter before—basically, anyone who doesn’t need an advanced professional tool. This type is easy to use because it gives you readings on only the unit you’re trying to measure!
• Clamp multimeters are best for professional use, and they measure electrical current (amps, volts, etc.).

Analog vs. Digital

What do professional electricians and serious DIYers have in common? Both groups of people should absolutely have a multimeter on hand!  

• Analog multimeters are the traditional design, and are today much less expensive than their digital counterparts. They use a needle point to display the measurement, which is sometimes easier to read and a bit more accurate.
• Digital multimeters are the newer design, and are usually more expensive than analog models. Rather than using a needle point, digital multimeters display readings on an LCD screen. Though these are a bit harder to read in bright lighting, you can find backlit models that counteract this negative feature.

Basic vs. Advanced

If value for money is what you’re after, then look no further than this digital multimeter from AstroAI. This is the kind of device that makes you do a doubletake and ask yourself, “That costs how much?”  This multimeter has many of the same features as the other units on our list—versatility, an easy-to-read display, a durable construction, and even a data hold function—at a steal of a price. While it’s not ideal for everyday professional use, this is the perfect multimeter for amateur electrical workers, school projects, or avid DIYers. It also comes with a 1-year warranty (and awesome customer support) to give you that extra peace of mind.
A basic unit will typically be able to measure three different units: voltage, resistance, and current. More advanced models will be able to measure those three units, in addition to temperature, capacitance, and frequency.

The Best Multimeter Tools

There are three main multimeter design types: fluke, autoranging, and clamp.

Accuracy refers to how accurate the measurement readings are. Most experienced multimeter users recommend an accuracy rating of at least ±2%, though a higher accuracy rating is ideal (especially if you’re a professional electrician).
You can find multimeters in a variety of price ranges, with the most basic models starting at around and advanced professional models running upwards of 0. That said, you should expect to spend anywhere from to 0 for a quality model that will stand up to casual or moderate use.
