Who are Zera?

ZERA develops, manufactures and sells devices and systems for producing, measuring, testing and calibrating electrical quantities. The focus lies in meter and instrument transformer test systems as well as e-mobility (testing of charging stations). Utilities, test laboratories and instrument transformer manufacturers are among their customers worldwide.

Founded as the “Zähler-Eich-und-Reparatur-Anstalt“(Meter-Calibration-and-Repair-Institute) in 1920, ZERA evolved from a service provider for meter calibration into a highly specialized producer of testing technology.
