Digital clamp leaker SRT140

SRT140 high accuracy clamp leaker is specially designed for measurement of AC leakage current; by adopting up-to-date CT technology and digital integration technology, it is a product with relatively small size, high accuracy and perfect function compared with similar leaker in the world. The leaker can be widely applied in electricity, telecommunications, meteorology, railroad, oilfield, construction, measurement, scientific and research teaching institute, industrial and mining installishments.

Clamp core of SRT140 high accuracy clamp leaker adopts special alloy, in addition, with utilization of magnetic shielding technology, it is basically free from influence from external magnetic field so as to ensure precision, stability and reliability of perennial continuous measurement.

SRT140 high accuracy clamp leaker can be used for AC line current measurement and on-line current measurement with voltage lower than AC 600V; It has functions as peak holding, data holding and data storage. For convenience purpose, it is an essential tool for electrician safety testing.
