EAN: 5036162186592 SKU: MARCMi210 Category: Tags: ,


A unique insulation clamp meter for the installation, testing and maintenance of domestic and industrial installations. This high specification clamp meter can perform insulation tests to 6G Ohms with 5 test voltages from 50V to 1000V.

The clamp provides True RMS measurement of AC current to 1500A and AC voltage to 750V. It will also measure DC current to 2000A and DC voltage to 1000V. The CMi210 has all the same test functions you would expect to find on a high specification multimeter with the added benefit of temperature measurement.
