ZIJJ-II Insulating Oil Dielectric Strength Tester

 

Overview

Based on the traditional oil testing machine, and combined with the advantage of electronic products on product measurement and control, the ZIJJ-Ⅱtypes of insulating oil dielectric strength testers are developed as ideal testers with compact structures for insulating oil breakdown voltage and dielectric strength measurements. Advantages include robust against interference and easy to operate.
