Need to measure current / amps without breaking into a circuit? Then you need a Clamp Meter,  Current Clamp, or another name is Clampmeters. First decide what to test and measure, is it AC currents or DC currents? We have Earth leakage clamp meters like the Megger DCM300E a high resolution a.c. current clamp, the Megger MMC850 Multi core clampmeter where you want to measure current without breaking a circuit or splitting cables. Our quality range of AC and DC amp meters are easy to use and tough. We are UK suppliers of the Megger DCM330 fork multimeter if you want to measure ac current in single unsheilded conductors less than 16mm in diameter. We supply AC and DC current clamp meters/ Amp meters from Kewtech, Metrel, Martindale, Multimetrix and Chauvin Arnoux.

AC/DC Clamp Meters

Multi Core Clampmeters

Multicore current clamp meters enable you to test or measure current without breaking electrical circuits or splitting cables or cores. Megger MMC 850 make AC current measurements in Single, two or three car cables including flat or round section cable easier.

True RMS Clamp Meters

We are suppliers of True rms clampmeters like the Kewtech KEW2046R that is highly accurate at measuring true rms ac currents up to 600A AC and Dc. consider the Kewtech KEW2056R if you need to measure true rms currents up to 1000 Amps.

Clamp Meter Adaptors

Current clamp adaptors from Kewtech and Fluke. Measure AC and Dc current with clamp adaptors and multimeters. Some work with oscilloscopes and tesing instruments from 0.1mA to 3000 Amps AC.

Earth Leakage Clampmeter

Earth leakage clampmeters are ideal for measuring ground / earth leakage currents in electrical systems. High resolution current clamps like the Megger DCM300E with 0.01mA resolution or Kewtech KEW2432 Digital Earth Leakage Clamp Meter with 0.001mA resolution.
