Contact resistance tester
Circuit resistance tester is a high-precision, digital switch testing instrument carefully developed by the company according to IEC standards and relevant national regulations, giving full play to its own technical advantages. The instrument adopts the technology of sine wave inverter and high power constant current switching power supply, and can measure the microohm contact resistance. Widely used in all kinds of switches and electrical contact resistance, circuit resistance and cable wire, weld contact resistance measurement.
Contact resistance tester
Експлоатационни характеристики
1. The test current is large and meets the requirements of the national standard for testing contact resistance.
2. High output voltage, wide measuring range.
3. The test current comes from the high-precision high-current constant current power supply, without manual adjustment, the test is fast and accurate.
4. The four-terminal connection method is adopted to effectively eliminate the influence of the test wire resistance on the test result.
5. The test speed is fast, and the data is displayed in about 10 секунди.
6. The instrument adopts 128X64 dot matrix LCD screen to operate Chinese display, което е удобно за използване от клиентите.
7. The instrument comes with a thermal printer, which can print the test data in real time.
8. Intelligent power management technology, the instrument always works in the minimum power state, effectively reduce the internal heat of the instrument, save energy.
