10 Best Multimeters of All Time

What kind of multimeter are you in the market to purchase? The greatest multimeters will provide you with the information you need fast and correctly. A subpar multimeter, on the other hand, will only offer you headaches.

Electricians tool kits commonly include a multimeter as a basic diagnostic instrument for everything from testing batteries to determining the amount of voltage in a circuit. Multimeters, on the other hand, are useful for DIYers who want to check their home’s wiring or fix electrical items. Additionally, they’re a useful tool for amateurs who want to fool around with electronic circuits and make things like pedometers and motors, as well as humidity sensors.

What is a Multimeter?

Multimeters are electronic devices that combine the functions of volts, resistance, and current measurement into a single unit (or lack thereof). When discussing multimeters, it’s important to distinguish between digital and analogue multimeters. There are only minor distinctions between the two, and while they both accomplish the same goals, their fundamental difference lies in the way they present the data.

Analog meter:

Using an analogue metre, a scale reading will be provided with a deflection pointer (a physical moving needle points to the measured value on a paper scale). There are no flashy screens here; instead, there is a glass panel with data printed on it. Traditional multimeters are still used by certain old-school electronic gurus, who prefer them because they can keep track of fast fluctuating readings.

Digital meter:

A digital metre displays a numeric reading on a screen, such as an LCD, so that you can see it clearly. With an analog-to-digital converter system (ADC), the analogue signal is converted into a digital one, which may then be processed and shown in numerical form on the metre screen, removing the need to understand needles and graphs. Nowadays, digital multimeters are significantly more prevalent than analogue multimeters due to the large range of options and functions they offer, as well as the generally higher levels of accuracy they normally provide compared to their analogue counterparts.

Auto-ranging multimeter

Voltage, ohms, and current are all measured in terms of units, just like any other object. Ranges are a term for groups of these increments, just as distances are. An auto-ranging multimeter is a digital instrument that can automatically determine the measurement range and show you the result. A multimeter with this feature makes troubleshooting components a lot easier for beginners and people who don’t have the time or need to sit and sort through the many ranges.

Manual ranging multimeter 

To get a correct result, a manual-ranging multimeter requires the user to specify a range rather than being auto-ranged. As a result, in order to get a reading, you need to be familiar with these ranges and where they appear in the project you’re working on. In general, an expert in their industry will be able to get more accurate readings with an auto-ranging multimeter than they would from an auto-ranging multimeter.

Clamp multimeter

Many of the features of a digital multimeter apply to a clamp multimeter. If you’re looking to measure the current in a live circuit, it’s an excellent choice. Measurements of voltage, resistance, and so on can be made by using the clamp. That reduces the risk of possibly life-threatening series readings.


A multimeter’s performance is determined by its specifications. Understanding the capabilities of different multimeters in terms of AC/DC voltage, current, and resistance is what we mean by specification.

Make sure you get a multimeter that has a CAT safety rating higher than what you need to use electrical appliances. Use a multimeter that can handle more current than your power supply can handle. This will prevent any potential dangers from occurring. True RMS value and low input impedance are important features to look for when purchasing high-quality multimeters.

Additionally, you should look for features such as blast shielding on the inside, shrouded banana plugs, extra-large backlights, auto shut-off, and input protection for Cat II-III, as well as a multimeter that is capable of all of these tests.


Make sure your multimeter is accurate before using it. In this context, accuracy refers to the maximum amount of inaccuracy that can be tolerated in the readings of a multimeter. The multimeter you buy should be able to test both alternating current (AC) and steady-state (DC) current.

Frequency measurement

Within a specific frequency range, some multimeters can measure frequency as well as current and voltage.

Energy capacity

Knowing the circuit’s energy capacity in advance is a good idea. Your multimeter’s ability to withstand transient voltage will be determined by this.


The number of digits at which a signal intensity can be assessed is referred to as the resolution of a device. It’s a measure of how small fluctuations in the input signal influence the output signal. If you’re looking for the most accurate reading possible, you’ll need more time to get there.

Input impedance

A multimeter with a wide input impedance range is an excellent choice for a digital metre since it provides accurate measurements and is easy to read. This is essential if you’re going to be taking measurements on any kind of electronic equipment that could be damaged. Ghost voltages are prevented in the low impedance mode.

It is preferable for LCD panels to have a backlit display that is easier to read in low light.

Temperature measurement

Get a digital multimeter with a two-differential thermocouple temperature function for frequent monitoring of thermocouples. Using this feature, two temperatures can be recorded at the same time.

It will be easy for you to choose the proper multimeter if you keep in mind the above seven factors.

How Do Multimeters Work?

Multimeters are one of the best options for job-site accuracy and adaptability because they are used for practically any electrical operations. They’re an essential part of every electrician’s toolkit, and using them on home electronics projects allows for far more precise work.

Even if you may find unique tools for each of the measures performed by a multimeter, the cost and complexity in transporting over a dozen different instruments make the multimeter a definite winner. It is safe to use specialist multimeters if you are an electrical technician with specific demands, such as checking HVAC systems.

In a nutshell, multimeters are a staple in electricians’ tool boxes for good reason: they’re versatile, inexpensive, and compact.

List of Best Multimeters

There is a large range of multimeters on the market, each targeted toward a certain project or specialty and capable of doing both basic and complex circuit testing. In contrast to the typical DIYer, electricians and HVAC technicians will benefit from the more advanced features of professional tools.

The greatest multimeters can be tested with your own hands, so keep reading to find out more about the best multimeters.

  • When measuring voltage, Auto-Polarity Checking might yield both positive and negative numbers.
  • Quickly determining whether or not the circuit under examination is an AC or DC one is made possible using the Voltage Checking feature.
  • Automatic On-the-spot measurements and electrical component troubleshooting are made easier with LCD displays that show readings from your multimeter’s operations.
  • Digital multimeters are known for their extreme precision, with some units measuring to four decimal places. A multimeter can provide you with the information you need to make informed decisions about your electrical work, no matter how large or little the project may be.
  • A piece of electrical equipment’s continuity checking will rapidly show any weak connections or broken wires. While soldering wires, this is particularly beneficial because it allows you to keep an eye on how the repairs are progressing.


For the most part, you don’t need to spend a lot of money on a multimeter that can perform all of the duties you need it to. We don’t know what features are crucial to technicians in other fields, but we can tell you which multimeters we think are the finest for the automobile industry.

  • A lot of multimeters don’t have backlights, so you’ll be working at night. For the sake of your tongue and teeth, you should invest in a multimeter with this feature if you can.
  • Your brain is an extension of the multimeter. Without that, it’s nothing more than a piece of plastic and electronic components. Your responsibility is to learn about diagnostic procedures and how to use them. The following are some guidelines for testing relays and transmission speed sensors, respectively.
  • To reiterate, multimeters are limited in their diagnostic capabilities, and you’ll need additional instruments to complete the task. A multimeter’s utility is enhanced with the addition of test lights, socket testers, and voltage probes.
  • Working with electricity teaches us how important diagnostic tools are. Check out our guides to Infrared Thermometers and Moisture Meters for more information on similar equipment.
