Device overview:
The UNT-NMI intelligent network instrument is a network power meter designed for the power monitoring needs of various enterprises. It can measure all common power parameters such as three-phase current, three-phase voltage, power, frequency and electric energy. In addition, this device can provide complete communication networking functions, analog uploading and other functions, which is very suitable for real-time monitoring systems. After years of engineering practice, UNT-NMI integrated intelligent meters have been widely used in power, chemical, paper, metallurgy, municipal, coal and many other fields, and the operation is stable and reliable.
Device features:
Full parameter measurement, can replace all single and three-phase electricity measurement instruments;
