  • PSC-150 is a TDS/EC controller that monitors and controls levels of Total Dissolved Solids (TDS) or Electrical Conductivity (EC) in water.
  • The controller has a maximum set point to help maintain a limit of TDS/EC allowed in the water.
  • If the TDS/EC level rises to the set point, the controller will activate a warning light, sound an alarm (optional) and switch the dry contact position from the normal position (to operate a valve, pump, etc.).
  • Once the TDS/EC level drops below the set point, this will deactivate the light and alarm and switch the contacts back to the normal position (normally open or closed).


EC Range: 0-9999 µS
TDS Range: 0 - 5000 ppm
Temperature Range: 1-75°C; 33-167°F
Accuracy: ±2%
Conversion Factor: NaCl (avg. 0.5)
Resolution: 0.1 µS/ppm (0-999); 1 µS/ppm (1000-9999)
