Product description
UNI-T’s UT258A is a 10000-count auto range clamp meter. It measures 0mA~60A AC/DC leakage current with zero mode, φ7mm jaw and RS-232 interface.
Main Features
UT258A is well designed for on-line measurement of DC/AC leakage current and current below 600V, which adopts latest CT and digital integration technology. Slender clamp is very suitable for places full of concentrated cables (such as, electric power metering system, high-speed rail system, automobile circuit maintenance and so on). Non-contact measurement ensures operation safety. The meter has mini shape with high accuracy, stable performance and perfect functions.
