Test Instrumentation

Clamp-on Ground Resistance Tester with USB Interface and Rechargeable Battery.

The Metravi CET-09 features Ground Resistance, Loop Resistance, Leakage Current measurements as well as judges Ground Faults. With USB communication interface, stored data can be uploaded to the computer, and through software analysis, reports can be printed or shared. It can measure up to 40A leakage current.

Real-time clock function displays present time, and it supports multi-parameter on-screen display function – displaying grounding resistance and ground leakage current at the same time, which makes measurements practical, convenient and efficient.

The Metravi CET-02EX is an Explosion-proof Clamp-On Ground Resistance Tester with a 32 X 65 mm Clamp Jaw.

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-200Ω.
• 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.
