High-Precision Insulation, Low-Resistance and Voltage Measuring Instrument for up to 40 TΩ with 10 kV Test Voltage
The METRISO PRIME 10 insulation tester has been developed for the detection of insulation damage and for protection against electric shock in electrical power supply networks.

It measures resistance up to 40 TΩ with a test voltage of 10 kV in accordance with EN 61557-2. Even in the case of high-frequency interference, absolutely precise measurement results are obtained. Faults can be quickly and easily pinpointed by means of localization with the new "pulse control" function. Insulation measurements such as PI, DAR, DD, stepped testing (SV), capacitance measurement, temperature measurement and measurement of protective conductor continuity are no problem. These measurement results can be graphically represented at the display immediately.
