The 6 Best Low Current Amp clamps (2023 reviews)

The hantek low current amp clamp is long-lasting, rigid and fits well with your regular usage like a dream. When you need to get an idea what the current looks like, it's a lot more useful than the typical amp clamp meter. This unit comes with a BNC connector, there are cables that adapt BNC to bananas. It is used to scope dwell on automotive coils without an issue. It will convert to amps automatically when you select the amp clamp in the setup bar.

The probe is set on a high sensitivity range of 1 mv per 10 ma, which will translate into 3000 ma pk to pk current. It takes 9V batteries so keep an extra handy. It is a nice instrument for measuring or viewing ac or dc current without opening the connection. There are plenty of clamp-on current meters which display the current directly.

Why We Like This:

Steady state input is very measurable
Good brand reputation

Best With High end DMM: PDI Low Current Amp Clamp

Buy on Amazon

The pdi low current amp clamp is capable of outshining several other clamp featured in this list in overall features in its price range. This is one of the smallest clamp heads you can find and it gets in some tight spots to read current. The 60 handheld 60 amp ac/dc current clamp probe allows you to measure ac and dc currents without disconnecting existing wiring. It clamps around a wire and it outputs a voltage in response. The low amp probe goes to low amp wire gages, no low amp wire is thick, so this probe is adequate.

This current clamp tool safely measures current from up to 60a without breaking or causing damage to the circuit or removing the insulation. The attenuator attenuates the voltage so your oscilloscope scale can adequately capture the wave form. It looks and feels well built. It provides a simple way to measure dc and ac currents without disconnecting existing wiring.

Why We Like This:

Works great for the verus pro scope
Especially useful for larger currents (> 10 amp) which typical multimeter does not handle
Good investment for long term

Best With Amp Clamp: Hantek Amp Probe

Buy on Amazon

Next on the list, we've got yet another clamp that manages to win our hearts. It's the hantek amp probe and it's widely considered as clamp that has the most suitable features. The 650 AC DC current clamp has a bnc cable end to be used with an oscilloscope. It is composed by permalloy and hall element, which linearly transform the ac or dc current to ac or dc current voltage. It allows to check ignition secondary on older vehicles (not coil-on-plug) and current draw while cranking. The probe responds in high frequencies also, so good to mesure fast amperage.

The current clamp range is set to 1mv/100ma, the actual current value is one hundred times of the measured data whose unit is ma. Its max range is 650 amps.

Why We Like This:

Power circuit measurement and malfunction analysis
Good accessory to allow full use of your scope
New and hot release

Best For solar: Jasleen Low Current Amp Clamp

Buy on Amazon

Jasleen makes beautiful and great clamp with classic and smartly choosen materials. This is an impressive measurement device. It has features for problem solvers and repair people. It is easy to make these measurements which would otherwise be very difficult and intrusive. The back clip makes it more portable, hang on your belt or pocket. These are easily dialed in by the control knob and there are detents to let you know when you arrive at the setting you desire. It comes with batteries which require a screw driver to install but a screw driver is included so all is well there.

It beeps at 19 minutes as a warning to override the shutdown if desired. It is handy for use if you have to work on a ladder or in other circumstances where you can carry it in your pocket.

Why We Like This:

Packs all the necessities in a smaller profile
Handy if you are looking for pocket sized
Delivers 0.1ma ac resolution and sensitivity
Numerous well thought out features for problem solvers and repair people

Best For HVAC: ALLSUN Low Current Amp Clamp

Buy on Amazon

If you often find yourself scrambling for appropriate and satisfactory clamp, allsun low current amp clamp should be your first option for buying. This probe allows measurements of live circuit current without having to disconnect, simply put the clamp around one of the wires. It measures the ac current in a conductor up to 33mm without interrupting the circuit, max. It works well compared to fluke and bk precision. It has two sensitivities, 1 mV/A and 10 mV/A, which, with the maximum output of 400 mV, translates to 400A and 40A full scale, respectively.

The reading is sensitive to orientation and movement of the clamp relative to earth's magnetic field, or other nearby magnetic fields, such as from a transformer. It is easy to accidentally bump and change the settings while taking a reading. This will be an occasional use tool, and smart people will always remove the battery for storage.

Why We Like This:

Noisy, but works well for relative testing
Needs a 9v battery, no auto shutoff
Nice meter, zeros out very well and is accurate

Best With Temperature: Autool Low Current Amp Clamp

Buy on Amazon

Best part: autool low current amp clamp costs comparatively low and it is available to ship in 24 hours. As long as you're not looking for high accuracy, quantitative results, this unit is pretty good. It is composed by permalloy and hall element, which linearly transform the ac or dc current to ac or dc current voltage. It is not only available for the detection or monitor of the possibly existing creepage, but for the measurement with little gap using its extended jaws.

The current clamp range is set to 1mv/100ma, the actual current value is one hundred times of the measured data whose unit is ma. The green LED will be lighting, indicating that the clamp is switched on to the current waveforms. It is necessary to turn the zero adjustment knobs on the clamp until the multimeter or scope reads zero.
