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 digital FlexProbe series can be used for TRMS AC current measurements. It is available with either a 6-, 10- or 24-in. sensor, has a measurement range starting at 20 mA and is designed for work in residential, commercial and light industrial applications.
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.
Fluke Networks’ Pro3000F filtered probe features a filter that removes signal interference at 50 or 60 HZ and their harmonics. It has a 10-mile range and a loudspeaker that allows toning through drywall.
Platinum Tools’ ToneSeeker TP250C tone tracer probe identifies wire and cable (when used with a analog tone generator) without having to make direct metallic contact with the conductor. It emits a clear tone as a cable is traced, and frequency filtering blocks out background noise.
