METRISO TECH :: Test instrument for insulation, low-resistance and voltage


The METRISO TECH insulation and resistance measuring instruments allow for quick and effective testing of protective measures in accordance with:

  • DIN VDE 0100

  • ÖVE-EN 1 (Austria)

  • SEV 1000 (Switzerland)

  • and regulations specific to other countries as well

Insulation measurement per EN 61557-2 / VDE 0413 part 2
Low-resistance measurement per EN 61557-4 / VDE 0413 part 4
Voltage testing and measurement up to 1000 V

Compact and rugged - for service calls under harsh conditions and laboratory use
  • Digital and analogue display, backlit

  • Intelligent filter - precise and measurement-dependent activation for the measurement of very high resistances

- beating, i. e. compensation of 16 2/3 Hz and 50 Hz interference
- attenuation of capacitive influences from power cables, etc.
- suppression of electric field influences
  • Signalling of dangerous contact voltage by means of LED

  • Indication of limit value violations by means of LED

  • Overvoltage protection - protects the instrument in the event of inadvertent connection to mains power

  • Fuse link for all resistance measuring ranges

  • New: Electronic fuse for protection of the low-resistance measurement RLO also protects the fuse link in the low-resistance measuring range in the event of faulty operation

  • One measuring point self-test with test resistance of 10 MO per EN 50110 / VDE 0105-100

  • Guard terminal for compensating surface current

The insulation measuring instruments are suitable for the following tasks:
  • Measurement of insulation resistance at voltage-free devices and systems, up to 1000 V

  • Testing of the resistance of earthing conductors, protective conductors and equipotential bonding

  • Checking of test objects for absence of voltage

  • Testing of electrostatic discharge capacity at floor coverings (using shielded measurement cables) - EN 1081
