Your PQube®3 is an analyzer, designed to monitor electrical energy systems and enviromental conditions.

With it you can detect problems and rate the impact on the voltage qualaity, which is an important measure for the reliability of your production. Look at the PQube®3 as a Black Box for the measurement of electrical energy and voltage quality. It is a combination of a power- and energy analyzer, a grid analyzer and a digital fault recorder

It combines the best attributes of all. It is easy to operate. You transfer the data via an SD-Card or a USB-Stick, just like with a digital camera, to a computer. No special software or license is needed for this.
