UNI-T UT272A Earth Clamp Meter

UNI-T UT272A Earth Clamp Meter

The UNI-T UT272A is a professional earth clamp meter designed for electricians, safety engineers, and grounding specialists who need a fast, non-intrusive method of measuring earth leakage and grounding resistance without disconnecting the earth electrode. Simply clamp around the grounding conductor and get accurate readings instantly — making earth resistance testing safer, faster, and more practical in the field.

Key Features

• Earth Resistance Measurement: 0.01Ω – 1200Ω without disconnecting the ground
• Earth Leakage Current: AC leakage current measurement for fault detection
• AC Current Measurement: Up to 30A leakage / interference current
• True RMS: Accurate readings on distorted waveforms
• Clamp Jaw Opening: Large jaw to fit earthing conductors and rods
• Display: Large backlit LCD for clear readings in all lighting conditions
• Data Hold & MAX/MIN: Capture and review peak readings
• Auto Power Off: Conserves battery during extended field work
• Alarm Function: Audible alert when readings exceed set threshold
• Safety Rating: CAT III 300V

Typical Applications

• Earth/ground resistance testing at substations, towers, and pylons
