HZC-2A DC Resistance TesterDetailed product description：

The DC resistance speed tester (micro ohmmeter) of HZC-2A transformer is a high-precision replacement product for DC single and double arm bridge. The instrument adopts advanced switching power supply technology, with a four and a half LCD display for measurement results and a three and a half LCD display for ambient temperature or test current values. It overcomes the disadvantage of other similar products having LED display values that are difficult to read in sunlight, and also has automatic arc suppression function. This instrument has the advantages of fast speed measurement, high accuracy, intuitive display, strong anti-interference ability, small size, low power consumption, stable and reliable test data, and is not affected by human factors. It is an ideal instrument for measuring the resistance of various inductive loads such as power transformers, as well as the contact resistance of low-voltage switches, wire and cable or weld interface resistance. Its measurement speed is more than 100 times faster than that of an electric bridge. The instrument is equipped with a rechargeable battery pack (12V), which can be used for both AC and DC, making it convenient for on-site and field testing.
