  • The PS-100 is a panel mount TDS controller that monitors and controls levels of Total Dissolved Solids (TDS) in water.
  • The controller has a maximum set point to help maintain a limit of TDS allowed in the water.
  • If the TDS 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 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).
