The FLIR CM42 600V 400A AC Digital True RMS Clamp Meter is a professional and affordable True RMS meter designed for commercial and residential electricians. The CM42 features AC clamp measurement; it is equipped with a bright backlit display for ease of use inside electrical panels. Accu-Tip™ technology delivers amperage measurements on smaller-gauged wires more accurately (to a tenth of a digit). CM42 offers MAX/MIN/AVG recording, frequency measurement, and electrical field detection to help determine voltage presence and relative strength of the field. Made with an over-molded, easy-to-grip design, the CM42 clamp meter is durable enough to withstand a two-meter drop, and its slim form factor is convenient to carry in your toolbag, wherever you go.
