General features  

The conductivity transmitter «TC-420» has been developed for qualitative control of the stored or in circulation fluids.

The measure is directly transmitted by 4-20mA. Three ranges are available :

  • 0-2000 µS
  • 0-200 µS
  • 0-20 µS

The rack DIN is designed to be inserted on rail in an electrical cabinet.
     
Applications
