MEWOI9300  Clamp on Leakage Current Monitoring Recorder


MEWOI9300 Three-Channel Leakage Current Monitoring Recorderis designed and manufactured for on-site simultaneous monitoring and recording 1-3 channel AC current or leakage current, it is composed of recorder host, current clamps, charger, monitoring software and communication cable, etc. Widely used in 380/220v power system, provide safe, accurate and convenient power instrument for power inspectors.

Host adopts LCD display, three channels with the same screen display, clear at a glance, there are Chinese and English operation interface two choices, suitable for different countries of engineering and technical personnel. The recorder equipped large capacity rechargeable lithium battery, display power energy with a three-grid mode, which can continues recording up to 7 days. With the function of system clock and super storage space, it can set the  monitoring and recording time on site, can store 200,000 sets of data, and has the function of setting the interval time of automatic storage, setting from 1 to 99 minutes.

Monitoring software has online real-time monitoring and historical query functions, historical data reading, consulting, saving, reporting and other functions.

The current clamp is made of Permalloy, and adopts CT technology and unique double layer magnetic shielding technology. It is almost unaffected by the external magnetic field, which ensures the uninterrupted monitoring long time with high accuracy, stability and reliability.
