Product Description

WRT DC Winding Resistance Tester for Power Transformer Testing

 

Product Description

WRT DC Winding Resistance Tester is a high precision new generation product that can replace DC Wheatstone Bridge and double-arm Bridge.

WRT Portable 5A 10A Power Transformer DC Winding Resistance Tester adopts the advanced starting power constant current source technology, uses four digit and half LCD display value and three digit and half LCD displays the ambient temperature or test current value, it overcomes the shortcoming that the LED display ambient value reading of other similar product is not convenient to read under the sun, at the same time it has the automatic arc extinguishing function.

WRT DC Winding Resistance Tester is an ideal equipment for measuring transformer winding and large power output inductor equipment
