Martindale CM84 AC/DC Clamp Meter

The Martindale CM84 is a high specification clamp meter providing AC and DC current measurements up to 1000A along with AC/DC voltage to 750V. The Martindale CM84 also has a useful DC current zero function. The CM84 is still light enough for use in one hand while still being robust enough for use in harsh environments.

Martindale's CM84 measures unusually high voltage readings of up to 1000V DC  and 750V AC which you would typically expect from a multimeter. Resistance to 40MΩ, frequency to 1MHz and continuity/diode testing are featured within this Martindale clamp meter. 

The CM84 has a 57mm jaw size suitable for large cables and conductors. The safety rating of the Martindale CM84 is CAT IV 600V and CAT III 1000V.
