HTHL-200P contact resistance tester

الوصف

Products features 

1.High current, adopts new power techniques, can output current long time and continuously , 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.Strong anti-interference ability, under strong interference, the last number displayed by the LCD within the range of ±1, with steady reading and good reproducibility. 

3. High precision: adopts double channels high-speed *6bits Σ-Δ AD to sample, digital signal processing technique, the maximum resolution up to 0.*1μΩ.

4. Intelligent: use high performance CPU, system can switch the measurement range according the size of the signal when testing, ensure the accuracy. The over-temperature protection circuit can auto stop output the current when the device exceeds the rated temperature to ensure the safety.

5. High quality: key components adopts imported components, uses temperature compensating circuit in perfect design which eliminates the effect to test results by temperature, meanwhile strengthen the resistance to shock by using the military connector.

6. Powerful : current could be *0A, **0A, **0A or **0A, measurement time 5s~**9s, more powerful than other equipments.
