The highlight of the Fluke 325 clamp meter is that it has a min-max button which gives you the minimum, maximum, and the real-time current reading of a conductor.

This comes in very handy if you are troubleshooting circuits and checking inrush currents.

#2 - Fluke T5-1000 Electric Tester

Most clamp meters have a jaw-like structure that wraps around a conductor, but not the Fluke T5-1000.

Its highlight is the OpenJaw current measurement feature which allows you to just put the conducting wire or cable into the cavity and the meter calculates the current.

As rugged as the Fluke 325, this meter is a lot less bulky and is amazingly portable. Users who trust Fluke for its reliability also appreciate the fact that its meters can work for decades even if used roughly.

That is an attribute Fluke has mimicked in this T5-1000 electric tester, which can also be used as a compact electrical tester.

Intended for heavy electricals and maintenance jobs, this is the meter to get if you want ruggedness, AC/DC voltage measurement, and portability.

#3 - Klein Tools CL800 Digital Clamp Meter

Less than half the price of Fluke, this little beast has an altogether different look than regular clamp meters.

#1 - Amprobe AMP-320 HVAC Clamp Meter

If you are on a budget, then get this Amprobe clamp meter that has all the bells and whistles of the above Fluke meter sans the mobile app.

Solidly built to give you accurate readings at even the highest ranges. It can measure both AC and DC current, voltage, temperature, and frequency.

Although we had issues with temperature calibration, it’s still a great deal when you look at the price.

It’s a very slender meter that can be used in areas that are hard-to-reach, but you will have to press hard on the thumb wheel as it is slightly stiffer than most models.

We believe Amprobe made it that way to ensure the user controls it properly.

The Amprobe AMP-320 is, however, best known for motor-phase match testing and inrush current measurement.

If you work in an industrial environment on a daily basis, then you know how a versatile meter like this can come in real handy. Go for it!

What’s more?

The app can also save readings and trendlines for future reference and the ability to share data in real-time.

With AC current measurement of up to 600 A (200 µA for DC) and temperature measurement from -10° C to 400° C, this true RMS meter is considered among the top clamp meters.

#3 - Fieldpiece HS33 Stick Multimeter

Priced almost similar to the Amprobe model above, this Fieldpiece clamp meter has few extra functions that make it a favorite among analysts.

In addition to the non-contact voltage check function, it also has min-max measurement and data hold feature – both of which make data collection a walk in the park.

The downside is the maximum current that can be measured, which is capped at 400 A for AC.

It also does not have a backlit display, which can again limit its uses. But it compensates for this with an intelligent design where the test probes can be fitted directly on the backside after use and detachable clamp.

If the Uni-T model still out of your budget, then we have the perfect alternative for you.

This Etekcity model is the cheapest on this list, and yet capable enough to take care of all your basic requirements.

In addition to AC and DC current and voltage measurement, it can also test resistance, diode, and continuity. Lack of capacitance or temperature measurement is the only drawback.

It might be surprising to learn that the Etekcity MSR-C600 also has data hold and a min-max button for you to analyze the quantities that you measure, a feature that is missing in most models in this price range.

Even though it has a one-year warranty, Etekcity meters are known to function for years and years as power conservation is one of its biggest fortes.

What is a Clamp Meter?

For the uninitiated, a clamp meter is a type of electrical testing tool that can measure the magnitude of a current through a conductor without touching it or disconnecting the circuit/system.

It uses a jaw-like structure that can be fitted around a conductor (an insulated wire, for instance) to detect the magnetic field generated by the conductor in real time.

It works on the principle of “transformer action” to detect a fraction of the current, and then converts the value into a higher resolution.

This contactless measurement feature is what makes clamp meter an essential tool for electricians working in high energy environments.

Types of Clamp Meters

There are different types of clamp meters available in the market, and users can select them depending upon their requirements.

There are meters that measure both AC and DC, models that also measure quantities like temperature and frequency, and also flexible clamps that can be used to measure current in hard-to-reach areas.

Clamp meters are majorly used in assembly lines, automation and HVAC environments, and areas where disconnecting the system for current measurement is difficult.

Clamp Meter vs Multimeter

Compared to general-purpose digital multimeters (DMM), clamp meters have the additional feature of contactless current measurement.

They are mostly similar in their functions with another difference being the resolution. DMMs give readings in higher resolutions whereas clamp meters are restricted to hundredth of a unit.

Having said that, it makes sense for a professional electrician to own both a DMM and a high-quality clamp meter.
