Reliable measurement at all sites

Metrum EQC (Energy Quality Control) are specifically adapted to be able to perform highly reliable energy controls on all sites; the unit is easily connected in for instance fuse boxes for measurement of voltage and current.

Measurement data is reported directly in a complete report template that can be submitted in event of customer complaint. In addition to the power measurement check, complete reporting according to the applicable voltage standards is included.
Metrum EQC

Could it be easier?

The portable EQC-instrument is designed to be user friendly and sufficiently small to fit for instant measurement of energy and power quality.

The unit is also easy to manage, just specify start value and press "Start measurement". As simple as that.
