UNI-T UT255C Wireless Large Current Fork Meter

Description

UNI-T UT255C Wireless Large Current Fork Meter The UNI-T UT255C Wireless Large Current Fork Meter presents a thoughtfully engineered solution for on-site current measurement, merging intuitive design with rugged construction. At its heart lies a uniquely shaped U-clamp that departs from traditional designs, allowing operators to enclose conductors effortlessly while maintaining precise alignment at the clamp’s base. This clamp works in concert with a detachable hot-stick extension, enabling safe engagement of high-voltage lines without sacrificing stability or control. Complementing the detector is a handheld receiver that mirrors readings in real time, streamlining workflows by removing the need to monitor the measuring head directly. Together, the two components form a cohesive system: the detector captures current through its U-clamp, then transmits the data wirelessly to the receiver up to 100 meters away. This separation grants technicians freedom of movement and clear visibility of measurements, even in confined or obstructed workspaces. Constructed with attention to longevity, the UT255C balances weight and durability; its surge-resistant housing and impact-tolerant connectors endure the rigors of field use, while the hot-stick’s moisture-proof and heat-resistant materials ensure reliable performance across varied environments. Whether navigating tight apparatus or scanning overhead lines, users find the meter’s ergonomic form and thoughtful balance reduce fatigue during extended tasks. Overall, the UNI-T UT255C embodies a harmonious blend of safety, convenience, and precision in large-current measurement. Features: Innovative U-shaped clamp design enables effortless conductor enclosure and precise centering for accurate measurements. Wireless data transmission up to 100 m separates the detector and receiver, allowing remote real-time reading. Data hold and storage functionality captures and records up to 99 measurement groups for later review. Adjustable connector and clamp jaws accommodate a wide range of conductor sizes and shapes. Detachable hot-stick compatibility provides safe, high-voltage operation, while direct clamping supports low-voltage line measurements. Robust hot-stick construction —lightweight, retractable, moisture-proof, high-temperature and impact-resistant, with superior insulation. Dual-purpose functionality serves as an alternative transformer turns-ratio tester by comparing primary and secondary loop currents.
