Straight into the wall socket
Metrum PQ Smart is developed for the simplest possible connection directly into the wall socket (230 V). Measurement commences automatically at connection and the instrument provides instant response via an integrated status-LED.
The PQ Smart-unit is a class A-instrument, hence it may be utilized as a reference instrument.
