NRJF-H Partial Discharge Detector

● High measuring sensitivity
● Wide range of capacitance
● Being well equipped for input unit impedance detecting and more variants of frequency bands (9 groups of frequency bands).
● After proper setting, the discharge impulse amount can be read directly.
● The indicating and digital meters are shown simultaneously.
● Adopt color LCD display graphics, compared with the traditional CRT, it has stronger waveform locking function, which is more conducive to observation and analysis graphics.
