Product Details
Digital Display Switch Circuit Breaker Contact Resistance Tester
Product introduction
ZXHL-300A Contact Resistance Tester is designed for measuring contact resistance of Switching Control
Equipment, using High-frequency switching power supply technology
and digital circuit technology. It is high precision and good
stability and can meet most power systems’ requirements in
high-voltage switches maintenance and high-voltage switches factory
contact resistance measurement.
Features
1. Large current: 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
displayed by the LCD within the range of ±1, with steady reading
and good reproducibility
3. Long service life: use high precision resistsance to eliminates
the effect from ambient temperature
4. Easy to use: small in volume, light in weight.
5. Optional to buit in printer or without printer.
