UNI-T UT276A+ Clamp Earth Ground Testers

14,500 EGP

Handheld clamp tester measures earth ground resistance and leakage current without disconnecting ground lines, featuring auto-range, data hold, and alarms.

Description

The UNI-T UT276A+ Clamp Earth Ground Tester is a reliable and efficient tool designed for measuring earth resistance and ensuring proper grounding in electrical systems. Featuring a user-friendly clamp design, it allows for quick and accurate testing without the need for disconnection, making it ideal for both professional electricians and DIY enthusiasts. Its robust construction ensures durability, while the clear display provides easy readability of measurements. This tester is suitable for a variety of applications, including electrical installations, maintenance, and safety inspections, helping users maintain compliance with grounding standards and enhance overall system reliability.

UNI-T UT276A+ Clamp Earth Ground Testers

The UNI-T UT276A+ is a handheld clamp-style instrument crafted to simplify earth ground testing by allowing measurements without disconnecting grounding conductors. Its slim, ergonomically curved housing shelters a robust jaw mechanism that gently opens around grounding conductors up to 32 mm in diameter. Once clamped, the tool injects a small, safe test current into the grounding system and senses the resulting voltage drop to calculate resistance providing instant feedback via its clear four-digit LCD.

The body of the UT276A+ is molded from impact-resistant polymer, ensuring durability in challenging work environments, while a textured grip area helps the operator maintain control, even when wearing gloves. A single rotary switch on the front panel lets the technician select the desired measurement mode, and large, raised buttons allow one-handed operation when quick readings are needed in tight spaces. Internally, dual-insulation construction isolates the user from live components, and built-in circuitry minimizes interference from nearby electrical noise. On-board electronics automatically adjust range and display stability, so readings settle rapidly without manual intervention.

The overall design compact, under 300 mm long and just over 1 kg strikes a balance between portability and ruggedness. In practice, the UT276A+ delivers reliable ground resistance data in seconds, making it an ideal companion for professionals who need fast, non-intrusive diagnostics of grounding networks.
