Earth Resistance Testers

2 products

The Earth Resistance Testers Collection provides tools for measuring soil resistivity and grounding system integrity. Essential for electrical installations, substations, and lightning protection systems, these testers ensure proper earthing to protect against electrical faults. With advanced designs offering three-point or four-point testing methods, they deliver highly accurate results. Used by electrical engineers, contractors, and compliance professionals, these instruments play a critical role in electrical safety and infrastructure reliability.

Frequently Asked Questions

An earth resistance tester measures the resistance between a grounding electrode and the soil to ensure electrical faults or lightning strikes safely dissipate. A low resistance value is critical for protecting personnel and equipment from dangerous voltages.

The collection features versatile units like the Digital Earth Resistance Tester (MT330) and the Earth Clamp Tester (MT332). For advanced diagnostics, the range includes the Fluke 1625-2 Geo Earth Ground Tester, which supports multiple testing methods.

A standard tester like the MT330 typically requires driving stakes into the ground to measure resistance through the earth. In contrast, the MT332 clamp tester allows for "stakeless" measurements by simply clamping around the ground wire, eliminating the need to disconnect the system.

The MT330 measures earth resistance up to 2000Ω and earth voltage up to 200V. It also functions as a multimeter, capable of measuring AC voltage up to 750V and DC voltage up to 1000V.

These instruments are built for rugged field use, featuring shock-proof overmolded casings and dust protection. They are essential tools in telecommunications, power utilities, oil fields, and industrial maintenance sectors.
