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.

Features

1. Automatic range switching, fast measuring speed (2s/time)

2. Wide measuring range: 0.0001mg/cm²~9.9999mg/cm²

3. English interface

4. 2.8′ true color LCD

5. Immediate display of ESDD, pollution class, RUSCD

6. Temperature self-compensation, auto display standard conductivity and ESDD under 20℃

7. Auto remove the salt content, which eliminates the requirements for cleaning fluid

8. Auto convert off line measured ESDD value to live line measured ESDD value

9. Can save hundred thousand groups of testing results, can save to SD card then read in PC

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
