high resolution manufacturer price winding resistance tester 20A

1. Product Name

Winding Resistance Meter HYZC-20

2. General Introduction
When the transformer is cross-connected, overhauled or some of its switches are changed, direct current resistance testing of the transformer winding is a must...In general, to measure the transformer winding or large power output inductor equipment, the traditional electrical bridge method and pressure drop method require much time and energy. Thus, to Shorten the measurement time and reducing the workload of testers, our company developed rapid direct current resistance tester. Which is designed with new power supply technology and stable performance, fast measurement, compact, easy to use, high accuracy, good data reproducibility. It is an ideal piece of equipment for measuring transformer windings and large power output inductor equipment.
