MEWOI7500 High Accuracy Clamp Leaker is specially designed for AC leakage current measurement. It obtains the latest CT and digital integration technology, with characteristics of small volume, high accuracy and perfect function. It is widely used in electric power, telecommunications, meteorology, railways, oil construction, measurement, scientific research and teaching unit, industrial and mining enterprises, etc. Special alloy is used as its sensor core, which applied magnetic shielding technology, results in a almost free interference of external magnetic field. RS232 interface is available on the meter. The meter can achieve online real-time monitoring and historical queries; in dynamic display, with maximum, minimum and mean value indications; also alarm value setting and alarm indication function, historical data reading, saving and print functions, etc. The meter can be used for on-line AC current measurement below AC600V, with the functions of peak maintaining, reading holding and data memory. In all, it is high accurate and easy and safe to use. |
