  • INQUIRY

JYM insulation resistance tester is used for on-site insulation resistance measurement. The instrument has built-in positive and negative bipolar high-voltage power supplies, with large output power and strong load capacity. It is suitable for insulation resistance measurement of samples with large capacitance, such as power transformers and cables.



Features:
1. Strong anti-interference ability. Using digital filtering technology, 5mA interference current at power frequency
It can still be measured accurately, and the test data is stable, which is suitable for on-site insulation resistance test
2. Built-in positive and negative bipolar high voltage output power supply. User selectable positive or negative high voltage output,
It is convenient for users to compare the insulation resistance test data under the same conditions
3. The short-circuit current is large. Not less than 100mA (this indicator far exceeds the traditional meg ohmmeter, directly
Short-circuit or short-circuit test voltage during measurement may cause instrument protection, special attention should be paid to safety)
4. Strong load capacity. The positive and negative high-voltage power supplies are at a voltage level of 5000V, and the current output is not less than 10 mA
5. Fast discharge. The instrument has a fast discharge function that can be achieved in milliseconds
Complete Discharge of Capacitor Test
6. Multi-level security protection to ensure personal and equipment safety. High-voltage protection: short-circuit, breakdown or high-voltage current fluctuation of the test product, cut off the output at high speed. Low voltage protection: misconnected 380V
7. Large screen backlit LCD display equipped with thermal printer, printing data is clear, fast, and noise-free. With USB interface, it is convenient to store and export data

8. With computer interface. Through this interface, measurement, data processing and report output are realized. One computer can control 32 instruments, which can be integrated into a comprehensive high-voltage test vehicle
