The Martindale CM87 is a high specification True RMS clamp meter, packed full of functions for the installation, testing and maintenance of domestic and industrial installations.

This robust clamp meter provides True RMS measurement of AC current up to 1500A and AC voltage to 750V. It will also measure DC current to 2000A and DC voltage to 1000V.The CM87 has the added benefit of temperature measurement between -20 to 1000°C and is supplied with a K-type thermocouple.

It also has the same test functions you would expect to find on a high specification multimeter to make this a comprehensive testing solution for electricians, maintenance and service engineers.
