Portable Precise salt density conductivity meter / HV insulator Salt Density Tester
ZX-YM ESDD Tester
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.
