Your advantages

  • Precision measurement with high basic accuracy of 0.02%
  • Measurement via Bluetooth at a safe distance from the object
  • Saves money because no interface cable is required, reduces on-site effort and increases safety as well
  • Optional METRAwin 10 PC software for measurement data recording, visualization, evaluation and documentation at a laptop/PC.


With its 22 multimeter functions, the instrument is suitable for universal electrotechnical use, especially in the areas of industry, service, electrical engineering, laboratory applications and research. The instrument can be used in the field and is equipped with an internal, mains-independent power supply (two 1.5 V AA batteries).

The Bluetooth interface makes it possible to perform measurements in environments which are hazardous for personnel, for example at rotating machines, in control cabinets with high-voltage or under extreme ambient conditions, such as those that prevail in climatic chambers.
