  • Description

    FLIR CM42 400A AC Digital True RMS Clamp Meter

    The FLIR CM42 400A AC Digital True RMS Clamp Meter is a well built, rugged clamp meter from FLIR’s CM4X range. This True RMS meter is designed for both residential and commercial electricians and it measures a whole range of electrical variables including voltage, AC current, frequency, resistance and diode. Its Accu-Tip™ technology helps measure current more accurately (±0.1 units) on thinner wires and it features data hold, zero function, and low pass filter for voltage measurement. Recording settings include MAX/MIN/AVG, frequency and diode so the CM42 is a truly versatile clamp meter. All results are clearly shown on the backlit LCD screen, a practical feature when working in dark places such as wiring cabinets.

    The CM42 has automatic electrical field detection to discover voltage and determine its strength for safety reasons. The narrow 30mm opening of the jaw brings access to awkward wiring whilst the slimline form and lightweight construction allow it to sit happily in a toolbox and be carried around by hand. The over-moulded grips and ergonomic design mean that the device is comfortable to use and the user can have confidence in the product as the CM42 can withstand a 2-metre fall and comes with a limited lifetime warranty. Overall, it is an affordable, reliable clamp meter.
