PSC-150: Extended Range EC/TDS Controller

HM Digital "PSC-150" is a well-known controller that includes an extended range, digital calibration, on-screen temperature, and tri-color display. The controller has a maximum set point to help maintain a limit of TDS/EC allowed in the water.

It has a built-in sensor for Automatic Temperature Compensation (ATC) ensures readings always be accurate at various temperatures. You can clearly check the reading measurements as it includes a bright 5/8″ L.E.D. display.

FEATURES:

• TDS/EC controller that monitors and controls levels of Total Dissolved Solids (TDS) or Electrical Conductivity (EC) in 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)
