Winding Resistance Tester HYZC-20S
The winding resistance tester HYZC-20S is the product of the latest generation for measuring the DC resistance of transformer and is optimally designed for measuring the DC resistance of the three-phase winding of the large-capacity transformer. It can measure the three-phase winding DC resistance of the transformer simultaneously.

2. As the winding resistance tester is provided with large-screen LCD and the graphical interfaces in Chinese, the operation is visual, clear and easy.
3. It is provided with panel type printer and large-capacity non-volatile memory, so the measurement results can be stored and printed out easily.
4. With good stability in data testing, speediness and perfect repeatability, it is the best choice for the on-site measurement of DC resistance of transformer.
