The 8 Best Clamp Test Meters (2023 reviews)

If you often find yourself scrambling for good meter, fieldpiece clamp test meter is your end point. It has virtually every parameter for electrical and thermal hvacr testing in one meter. It works as intended and is very dependable. It is great clamp on meter for daily use in hvac. It can read ohms, volts and amps, as well as temp reading if you use acc. This point is unaccurate and all over the place. It comes with removable gold plated tips to connect with fieldpiece accessory heads. It is easy to use, even for beginner techs.

Best With Inrush: Kaiweets Clamp Test Meter

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate meter. The kaiweets clamp test meter is exactly that - it's a simple meter that hits all the right notes. This is an inexpensive DC (and AC) clamp meter. It will work with clamp or probes. It is easy to use for labs and factories and household. It can't be easily propped up to free your hands. The DC ammeter clamp is very big and convenient. It is easy to measure DC current with a clamp if it uses a Hall Effect sensor for the DC measurement. The backlight is handy, the probes are nice, the thermal probe works, and it comes with a decent case too.

This is an excellent tool for DIY enthusiasts, and anyone who needs a reliable and accurate clamp meter.

Why We Like This:

Nice for working on dc currents such as car batteries/cables
Recommended for anyone who doesn't need more than 1/10th of a amp accuracy
Delivers what they promise

Best With Multimeter: Klein Tools Clamp Test Meter

Buy on Amazon

Not everyone likes to purchase meter for their regular usage, but the klein tools clamp test meter would be an anomoly. This meter can not measure dc current flow in both polarities. It features a low impedance (loz) mode for identifying and eliminating ghost or stray voltages, and has a dedicated mode for capturing inrush current. It can measure resistance, Amperage, and up to 2000 Amps. It is a bit on the bulky side, but it does make it easy to read.

It is a good value meter for general electrical use. It can be used to test volts and amps. The klein is faster and very close in accuracy but carrys way more features. It features include frequency/hertz measurement.

Why We Like This:

Lighted display, in-rush ability, auto ranging, ac and dc current measuring, nice soft case
Has all the features in one instrument, hard to beat that
Lot of satisfied buyers

Best For checking Amp draw: GTC Clamp Test Meter

Buy on Amazon

Not everyone likes to purchase meter for their daily purpose, but the gtc clamp test meter would be an anomoly. DC clamp-on current meters are great for when you want to measure Amperes flowing through a wire but don't want to cut it to insert a "classic" Amp meter in series. It is great tool for measuring parasitic draws and ac/dc voltage measurement up to 600 volt. It also works good on ac/dc house current draw, just clam around one wire at a time.

This meter is great for checking low voltage drains on your battery. The electronics that measure DC current are sensitive to temperature fluctuations and the offset (zero value) will change as the instrument cools or warms. It's well made and works great. It is perfect for getting in tight spaces to see what the line is doing.

Why We Like This:

Works great for quick amp checks
Great for automotive and diy projects
Good brand reputation

Best With DIFFERENTIAL Temperature: UEI Test instruments Clamp Test Meter

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate meter. The uei test instruments clamp test meter is exactly that - it's a simple meter that hits all the right notes. Clamp meters are pretty handy for measuring high currents in the breaker panel and under your car's hood. When you unbox this UEI meter, the first thing you will notice is the weight and the sturdy feel of this unit, which is built very well with a heavy duty case that will withstand years of use. It includes a work light to illuminate dark areas and test lead storage for easy transport. It has a resistance setting and a conductivity setting. It is also non-contact voltage to identify live lines.

The resistance setting is silent and can be set for auto or manual ranging. It can take two temperatures at once and also give a deltaT/temp rise reading using the thermocouples. The added features allow this volt meter to also be used in the hvac trade.

Why We Like This:

Has a magnet on the back
Can measure both current and voltage at the same time
One of the new comers and featured product

Best For air conditioner: Fluke Clamp Test Meter
