Product introduction

NRZK-2000 series vacuum interrupter tester is used to calibrate the vacuum degree of the vacuum interrupter, with single-chip computer as the main control unit, the testing process is fully automated. The sampling design of the instrument uses the ion charge to do the calibration, instead of using the current peak value to do the calibration in the past. Thus, effectively inhibited the disturbances of transient power during the test, so the test is stable and reliable. Because the instrument adopts computer as the main control unit, the instrument can conveniently deduct the leakage current caused by the environmental factors.

NRZK-2000B type vacuum interrupter tester is an upgrading and improved products after the several field test. The product has the advantages of compact structure, light weight, shorter testing time, higher measuring reliability and stability, higher accuracy and more perfect function.

Alternative name
vacuum degree tester, HV switch vacuum switch tester
The Characteristics of the products

1. can make quantitative measurement for vacuum degree of all models vacuum switch arc-chutes .
2. Need not disassemble the vacuum switch during the field test. 
3. High precision.
4. With LCD, easy to operate.
5. Can save, print and review the test results. 
6. The device with RS232 communication interface, connect with the PC can download the vacuum degree-ion current curve, can estimate the life.
7. Light in weight, easy to carry
