The Metravi CET series Clamp-on Ground Resistance Testers feature:

  • Self-test facility. No need to wait a long time to boot. Ready to use immediately after being switched on.
  • Breakthrough relay self-test mode, using the most advanced processing algorithms and digital integration technology, fully intelligent.
  • Handheld device, easy to carry. New design, panel operation with 6 buttons, better performance. Loud sound and light alarms; “beep—beep–beep –” alarm sound.
  • Improved interference signal recognition indicator. Improved anti-jamming capability and test stability. Data storage: 99 Units. Wider range: 0.01Ω-1500Ω.
  • Lower power consumption: Maximum operating current does not exceed 50mA. Are widely used for grounding resistance measurement in power, telecommunications, meteorology, oil fields, construction industries and electrical equipments.
  • In the measurement of a grounding system with loop current, it does not require breaking down the grounding wire and needs no auxiliary electrode.
  • Safe, fast and simple to use.
  • Can measure ground faults beyond the reach of traditional methods and can be applied in situations not in the range of traditional methods.
  • Can measure integrated value of the grounding body resistance and the grounding lead resistance.
  • Equipped with long jaws (for some models). Long jaws are particularly suitable for testing grounding with flat steel.
  • Also able to measure leakage current and neutral current in the grounding system.
