MARCM57
This high-performance Martindale CM57 is an AC clamp meter with TRMS which ensures more reliable readings. The CM57 covers a whole range of tests from AC current unto 600A, AC/DC voltage up to 600V, resistance with continuity test, capacitance, frequency and diode testing, and with the inbuilt smart function, the meter will automatically switch between resistance and capacitance measurements.
It features a 25.4mm opening jaw which has a built-in non-contact voltage sensor for detecting the presence of AC voltages making it even quicker, easier and safer!
