Our new high-end products insulation tester and earth tester

METRISO PRIME 10

High-Precision Insulation, Low-Resistance and Voltage Measuring Instrument for up to 40 TΩ with 10 kV Test Voltage!

Applications and areas of application

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.

Benefits for the customer

  • COST SAVING – a tester for many measurement tasks

GEOHM PRO / XTRA

High-Precision Earthing and Low-Resistance Measuring Instrument (GEOHM XTRA with GPS)!

Applications and areas of application

The GEOHM PRO / XTRA is capable of much more than just easy and reliable implementation of the most common methods of earth measurement. The measuring method for testing lightning protection systems under highly realistic conditions based on various types of the pulse measuring method is noteworthy in this respect.

Thanks to extensive measuring accessories, earth measurements and resistance measurements can be easily implemented in any environment at any earthing or lightning protection system without

disconnecting the earth electrode. Furthermore, a professional earthing analysis can be conducted on the basis of measured interference voltages and interference frequencies.

The GEOHM XTRA is additionally equipped with an integrated GPS module for saving the positions of devices under test.

Benefits for the customer

  • COST SAVING – a tester for many measurement tasks
  • TIME-SAVING – easy troubleshooting by professional ground analysis.
  • EASY HANDLING – through intuitive user guidance, graphic display and help function.
  • FAST REPRODUCIBILITY – through modern data management.
  • ROBUST BY MEASURING CASE – use in harsh environments and easy transport.

Benefits for our sales

Expansion of our GEOHM product portfolio. New applications of medium-voltage grid, wind power and photovoltaic plants.

The product is very innovative which will strengthen our image as an innovative manufacturer for high-quality measurement technology.
