AEMC’s MN375 AC current probe has a 0.78-in. jaw opening and accommodates conductors up to 250 kcmil. Polycarbonate materials and ultrasonic welding are used throughout for ruggedness. It uses a nickel core to improve accuracy and phase shift on the low end of the measurement range.

Megger’s Iclamp current probe features jaws for cables up to 52 mm. There is overvoltage protection of the output terminals, and it is suitable for leakage currents. It can be used to measure current in the range from 1 mA to 1,000A.

AEMC’s AC/DC MR525 clamp-on current probe can operate in temperatures between 14°F and 131°F. It indicates the shape and amplitude of the current measured in the form of a voltage. It features a range overage and power supply indicators, auto standby mode and a micro-USB connector for an external power supply.
