Our calibration customer data base includes many of the largest companies and test laboratories in the world.
We specialize in system calibration and integration for Harmonics & Flicker, dips & interrupts, and other immunity tests. Systems often also include harmonics and inter-harmonic disturbances testing, voltage variations, frequency variations, etc. Laboratory power sources are tested and calibrated in accordance with IECEE CTL-OP-110 and/or OD-5010. With a combined experience of 40 years in testing instruments and applications, we provide unrivaled expertise. Our founder received the prestigious John M Fluke award for his work in instrumentation standards, and the IEC 1906 award for his contributions to IEC standards and technical reports.

Immunity and emission requirements apply to electrical and electronic equipment used to be connected to the public supply in the home, business, office of factory. Generally, these test requirements apply to 50 Hz or 60 Hz public supply networks. Testing & calibration is done per the measurement standards IEC 61000-4-7 and IEC 61000-4-15. We participate in several IEC and UL standards committees, and contributed to the measurement standards and the technical calibration reports IEC TR 61000-4-37 and IEC TR 61000-4-38.

Solar inverters have to meet IEC, UL, or country specific standards. Electric and hybrid vehicle chargers also have to meet emissions and immunity power requirements. We participate in international and US ( UL STP-1741) committees dealing with dispersed generation.
