Professional Grounding Analysis Made Simple

The Uni-T UT275 Clamp Earth Ground Tester is an essential instrument for electricians and maintenance engineers who require fast, accurate, and non-intrusive grounding measurements. Designed to streamline field testing, this specialized tool allows for the measurement of earth resistance and leakage current without the need to disconnect earth wires or deploy auxiliary grounding rods.

Equipped with a high-precision sensor and a 10,000-count backlit LCD, the UT275 provides a resistance measurement range from 0.01Ω to 1000Ω. Its advanced clamp-on technology is particularly effective in high-noise environments, ensuring reliable data for critical infrastructure across power distribution, telecommunications, and industrial sectors.

Why It Matters

In traditional grounding tests, disconnecting a system to measure resistance can introduce safety risks and significant downtime. The UT275 eliminates these obstacles by using a dual-insulation clamp design that measures resistance through induction. This means you can maintain system integrity while ensuring the safety of personnel and equipment, making it the preferred choice for Australian industrial job sites.

Tradie Pro Tip

To ensure the most accurate readings with any clamp tester, always check that the jaw faces are completely clean. Even a small amount of dust or oxidation on the mating surfaces of the clamp can increase the magnetic resistance, leading to an artificially high ohm reading. Use the included test ring before your first measurement to verify calibration.
