Conductivity Controller

Detailed Product Description

1 general introduction

This series of instruments are industrial on-line instruments for measuring and controlling conductivity.It applies widely to the measurement and control of pure water in the fields of pharmacy, chemical industry, electronic industry, food industry and beverage industry.

The characteristics of the instrument:

1.)   cut display of conductivity and temperature.

2.)    automatic digitalized temperature compensation, direct display of conductivity value base on  25.

3.)    input of measuring range and electrode constants through keyboard

4. )   setting maximums in the entire measuring range and setting relays' return difference.

5. )    output of insulated 420mA current signal, convenient to long-distance transmission of   data.
