The Teledyne FLIR CM44 600V/400A AC True-RMS Digital Clamp Meter with Type K Thermocouple is a professional and affordable True-RMS meter designed for commercial and residential electricians. The CM44 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). CM44 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 CM44 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.
