JKVT90 portable oil pressure calibration device

Main functions and features
1. This device is designed specifically for insulation oil withstand voltage testers.
2. The voltage divider unit is composed of high voltage and high impedance glass glaze resistors, which are small in size, light in weight, and have high output accuracy.
3. The distance of the high-voltage contact point can be adjusted to adapt to the structure of the voltage tester from different manufacturers.
4. 7.0-inch resolution 1024 * 600 industrial grade high-definition color touch serial port screen, suitable for harsh environments, strong magnetic interference, and outdoor work environments.
5. It can display the effective value, frequency, boost speed, peak factor, waveform of the output voltage, as well as the working status of the calibration device.
6. Large capacity lithium batteries and lithium battery charging modules can work continuously for more than 8 hours.
7. Adopting a temperature and humidity composite sensor with calibrated digital signal output. Has reliability and long-term stability.
8. During use, there is no need to connect a high-voltage line to quickly verify the output voltage of the oil pressure tester.
