Hangzhi Precision

World's Leading High Precision Current Transducer and Tester Supplier

One Stop Solution for High precision current measurements

About Us

We design and manufacture precision current transducer and testers with top accuracy

Hangzhi is a high-tech company located in ShenZhen, China, innovatively developed and designed high precision 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.

Our High Precision Testers

We are the only portable high precision current test manufacturer on the market

Calibration for battery discharging test equipment

HIU AC / DC testers are widely used by EV battery OEMs for calibration the battery discharge testing equipment in their factory as a critical quality control process. 

Electrical Laboratory / Calibration

PSM electrical standard testers are ideal for the high accuracy DC current measurement in the electrical laboratory and calibration purpose.
