Martindale CM82 AC Clamp Meter

The Martindale CM82 is a high specification 1000A clamp meter, a compact meter that provides accurate measurement of AC voltage to 750V, DC voltage to 1000V and AC current to 1000A. It is light enough for use with one hand but still robust enough for use in harsh environments.

The Martindale CM82 is performs the following measurements: resistance measurements to 40MΩ, capacitance to 4mF, frequency to 1mHz and a 400Ω continuity test and diode test.

The CM82 is both manual or auto ranging and with a large 51mm clamp jaw size opening making it suitable for use within an industrial ewnvironment where larger cables and conductors are found. The CM82 also has a hold function which stores the last reading obtained for temporary recall.
