JK900 zinc oxide arrester resistive current tester

The JK900 zinc oxide lightning arrester tester is used to test the full current and resistive current of zinc oxide lightning arresters. Based on the comparison of test parameters, it can determine whether there are dangerous defects such as insulation moisture and valve plate aging inside the equipment. It can be used for online live testing and production process inspection.
Main functions and features:
1. Adopting a large screen true color LCD, the display is clear under strong light.
2. The instrument has a perpetual calendar and power down storage, which can store test data for easy reference.
3. The instrument is equipped with a USB interface and can be stored on a USB flash drive.
4. The instrument is equipped with a micro printer that can print test results.
5. Equipped with phase to phase interference testing function, it can effectively remove phase to phase interference.
6. Built in large capacity lithium battery, with two power supply modes: AC and DC.
7. It can measure both three-phase and single-phase simultaneously.
8. The instrument has two measurement methods: wireless and wired.
