Hangzhi is one of the high precision current transducer manufacturers located in ShenZhen, China, innovatively developed and designed high precision AC/DC current transducers & standard testers with the combination of technologies including multi point zero-flux, flux excitation close-loop control, self-excited fluxgate technology and multi-close loop control. The current transducers can detect both DC flux, AC flux, and high-frequency ripple with a built-in high-frequency ripple sensing channel, which allow the transducers have both high gains and accuracy at the full bandwidth.

Hangzhi design and manufacture wide range of current transducers and testers for the DC and AC current, voltage and power measurement to meet the requirements in different industries, such as medical, railway, renewable energy, EV/HEV charging stand and calibration & testing etc.
