RTZRC-20A Fast DC Resistance Tester is designed to measure DC resistance of inductive devices, such as transformers and power inductors. It uses newtech measurement and arc suppression, so its measuring speed is faster than other similar competitive products.
It can effectively find transformer coil selection, welding, loose joints, missing shares, disconnection and other manufacturing defects and running there is a hidden danger. In order to meet fast-transformer DC resistance measurement needs, our company developed RTZRC-20A DC resistance tester. The instrument uses a new power supply technology, small size, light weight, high output current characteristics. Machine controlled by a microcontroller, a high degree of automation, with auto discharge function. Instrument testing of high precision, easy to operate, can realize the rapid measurement of transformer direct resistance.
