DTZJ series of Insulating Oil Tester are designed to test the insulating strength of insulating oil which is used as dielectric in many types of transformer and switch. Furthermore, the tester can be also used to test the insulating strength of other dielectric when it is put between the two electrodes of the tester.

Features
Using dry-type HV transformer, small and light.
Organic-glass cover for safety and observation.
Stir the oil sample using electromagnetic mechanism.
Fully automatic testing process: Auto stirring, Auto standing, Auto raising HV, Auto flashing notice when breakdown, and Auto returning to zero, and then Auto repeat the full process N times.
Stirring time, Standing time and repeating times can be set freely.
High accuracy, High reliability.
Built-in printer.
Auto shut off HV when breakdown.
Auto shut off HV when safety cover is opened.
