MEWOI7300E DC Leaker Current Clamp Meter is specially designed for measurement of DC leakage current, DC low current; which resolution can reach 0.1mA, 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 leakers in the world. The leaker could be widely applied in those fields as electricity, communications, meteorology, railroad, oilfield, construction, measurement, scientific & research teaching institutes, industrial and mining establishments, car circuit maintenance. MEWOI7300E DC Leaker Current Clamp Meter also named: High Accuracy DC Leaker Current Clamp Meter, Car DC Leaker Current Clamp Meter. This DC Leaker Current Clamp Meter obtains one USB interface. With the help of the software that we provide, many functions are available. For example, on-line monitoring, historical data inquiry, active curve drawing. There are also functions like saving to documents and printing when connected to PC. It also has functions such as peaking holding, data holding, data storage and adjust zero. |
