Martindale CM84 Clampmeter

Description

The CM84 is a high specification 1000A clamp meter, packed full of functions for the installation, testing and maintenance of domestic and industrial installations. It is light enough for easy one handed operation but still robust enough for use in harsh environments.

This compact meter provides accurate measurement of AC voltage to 750V, DC voltage to 1000V and AC current to 1000A. It has the same test functions you would find on a high specification multimeter making this clamp a comprehensive testing solution for electricians, maintenance and service engineers.

This has the added benefit of DC current measurement to 1000A and has a useful DC current zero function.
