The device is used for anti-pollution flash-over testing in electric power system, which can especially measure insulator surface ESDD ( equivalent salt deposit density ), and also can measure liquid conductivity and temperature. It is featured with high precision, wide measurement range, convenient operation and usually used in electric power system or teaching and science research department.
Features
1. Automatic range switching, fast measuring speed (3s/time)
2. Wide measuring range: 0.0001mg/cm2～9.9999mg/cm2
3. English interface
4. 480*272 (5′) color touch screen
5. Can display and print out the ESDD, conductivity, temperature, pollution class, RUSCD ( reference unified specific creepage distance )
6. Temperature self-compensating, auto display standard conductivity and ESDD under 20℃
7. Auto remove salt content, which reduces the requirement for cleaning fluid.
8. Auto convert off line measurement value of ESDD to live line measurement value of ESDD
9. can store hundred thousand groups of testing results, can export data to U disk and print out
10. single record can be browsed, deleted, or exported, the total records can be deleted
11. Built-in 2600mAh Li-battery, it is suitable for field work
