FLIR CM46 TRMS Clamp Meter With DC Current


The FLIR CM46 clamp meter is designed for commercial and residential electricians. Featuring both AC/DC measurement, the meter is equipped with a bright backlit display for use inside electrical panels. Accu-Tip™ technology delivers amperage measurements on smaller-gauged wires more accurately — to a tenth of a digit. The meter also offers MAX/MIN/AVG recording; measures DCµA, temperature, capacitance, and frequency; and has electrical field detection to help you determine voltage presence and relative strength of the field.

A high precision, professional-grade clamp meter suitable for measuring both AC/DC current up to 400A, the FLIR CM46 delivers high accuracy results even when testing on irregular AC waveforms, thanks to true RMS included as standard. Generous jaw opening of 30mm means the CM46 can be used in a wide variety of applications and FLIR's unique Accu-Tip mode allows you to measure on smaller-gauge wires with exceptional levels of precision.
