HM6090-200A Contact Resistane Tester

Circuit Resistance Tester,
Switch Circuit Resistance Tester

Product Description


The intelligent circuit (contact) resistance tester is designed by combining high-frequency switching power supply technology and digital circuit technology. It is suitable for measuring the circuit resistance of switch control equipment. The test current adopts DC 100A and 200A, and the circuit resistance can be directly measured at a current of 100A or at a current of 200A. The final test results are displayed digitally.


  1. The instrument has a wide resistance measurement range and high resolution.
  2. The output current of the instrument adopts a high-precision 200A switching power supply, which is automatically adjusted and has a fast measurement speed.
  3. Integrated chassis design, simple structure, light weight, and easy to carry.
  4. Adopting a 5.0 inch 65K color touch screen, easy to operate.
  5. Built in large capacity non volatile memory, capable of storing 500 sets of data.
  6. Built-in high-speed micro thermal printer, capable of printing measurement data.
  7. Built-in high-precision clock, real-time display of time.
  8. Equipped with USB flash drive storage function.
