Who are ZERA?
Eich-und-Reparatur-Anstalt.
Our focus is the development and
manufacture of test systems for
measuring voltage, current and
power. We do not produce
electricity meters or instrument
transformers, but the test solution
for them. Therefor, we are able
to guarantee our absolute
neutrality in this highly sensitive
field. We are committed to the quality seal ,,Made in Germany" for more than 90 years.
What does ZERA stand for?
Over apperiod of several decades,
ZERA has changed from
a service company for meter
calibration into a highly
specialished producer of test
equipment. Our solutions
have helped to shape
technological developments in
testing. ZERA test systems fall
into the highest posible
accuracy classes and are
recognised worldwide.
Thus, for example, our calibration
laboratory was granted
accreditation by the German Calibration Service (DKD) at the beginning
of 2000 - an accreditation accepted by metrological laboratories all over
the world. On this basis, we have been developing and manufacturing
highest precision portable and stationary test systems for decades.
