Quality & Testing

Elements are measured before they ship.

Our test area reads voltage, current and power on elements under load. Test points for your project are agreed during drawing review.

05Quality lab

Measured on a test bench, not assumed.

Our test area reads electrical values from elements under load, so the sample you receive can be checked against the figures agreed in the drawing.

  1. 01

    Live electrical readings

    Elements are powered on separate test channels while voltage, current, power and power factor are read from dedicated meters.

  2. 02

    Channel-by-channel testing

    Each channel has its own breaker and indicator, so several elements can be tested side by side.

  3. 03

    Points agreed with you

    Test points for your project are set during drawing review and applied to the sample.
