BENEFITS

Perfect for pass/fail testing – you set the allowable PD

level and the unit determines pass and fail.

Simple to use – 8 buttons on the front panel are all you

need to operate the detector.

Straightforward replacement – if you’ve got an old

analogue unit and need a cost effective, simple replacement.

Multiple detector – with the data acquisition

software you can operate and monitor multiple detectors at
the same time.

Integrated test systems – because of it’s compact design

and functionality this unit is ideal for an integrated PD test
system including an AC power supply.
