A ground resistance tester is an instrument used to measure the electrical resistance between an earthing system and the actual ground. This type of measurement is essential to ensure electrical safety in installations, preventing electric shocks, fires, and ensuring the proper operation of protective devices such as circuit breakers and surge protection devices (SPDs).

In our online store, you will find the ideal ground resistance tester for accurately measuring the resistance of specific earthing systems, as well as resistances in ohms. This portable, battery-operated device features functions such as a timer (e.g., 3 minutes), data-hold function, and a multifunctional LCD display.

The tester offers three measurement ranges: 20, 200, and 2000 ohms, with resolutions of 10 mΩ, 100 mΩ, and 1 Ω, respectively.

The measuring system uses a constant current inverter (approximately 800 Hz, 2 mA) to determine ground resistance, and a rectifier (approx. 5 kΩ/V, range 40 to 500 Hz) to measure ground voltage. Compact and versatile, the tester facilitates identification between ground, phase, and neutral conductors.

It is an essential tool for the quick detection of faulty connections, outdated electrical installations, or failures in the grounding conductor. Order your ground resistance tester now from our online store.
