Transformer DC Resistance TesterDetailed product description：

The ZGY-III transformer DC resistance speed tester is a recently developed third-generation product. Advanced large-scale analog-to-digital conversion integrated circuits are used to achieve high measurement sensitivity; The digital display is intuitive and clear; The automation level of the instrument is high; Equipped with automatic digital zeroing; There is an automatic protection function for various misoperations. Speed measurement is several tens of times faster than an electric bridge. Very suitable for measuring the DC resistance of inductive samples such as transformer windings, transformers, and motor windings in the power industry sector. It can also be suitable for measuring switch contact resistance, cable resistance, and general resistance.
