High Precision Hand Held ESDD Tester Equivalent Salt Deposit Density Tester

Introduction

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.
