Product Introduction

1. Large current: This contact loop resistance tester can realize sustainable output test current from a constant current source, which overcome the malpractice of instantaneous current of the impulse type power, can effectively break through the oxide film of the switch contact, get accurate test results.

2. High stability. under strong interference, the last number of display can be stabilized within ±1word range, steady reading and good re-producibility.

3. Long service life: use high precision resistance to eliminates the effect from ambient temperature
4. Easy to use: small in volume, light in weight.
5. Optional to build in printer or without printer
