Hitec Special Measuring Systems was the first introducing a revolutionary high precision current measuring system based on the zero-flux principle. The bipolar Zero-Flux measuring system optimizes the concept of galvanic separated measurement of direct and alternating currents with exceptionally high precision.

Today many thousands of these systems found their way in scientific, HVDC, industrial and healthcare applications all over the world. They have earned the reputation of being the ultimate systems for measuring electrical currents.
