The insulation measuring instrument is suitable for the following applications:

  • METRISO Application Measurement of insulation resistance at voltage-free devices and equipment, up to 1000 V
  • Testing of the resistance of earthing, protective and equipotential bonding conductors
  • Checking of test objects for absence of voltage
  • Testing of floor covering electrostatic discharge capability (using shielded measurement cables) – EN 1081

Simplifies your measuring tasks:

  • Warning for hazardous shock voltages
  • Quick test with red LED indicator on the instrument
  • Acoustic signal generation in the event of limit value violations
  • Measuring voltage: 250, 500 or 1000 V DC
  • Measuring range: 10 kO … 10 GΩ
  • Low-resistance measurement: 0.01 … 10 O with automatic polarity reversal
  • Voltage measurement up to 1000 V AC TRMS / DC
  • Electronic fuse for protection of the low-resistance measurement
