Cooling Tower pH Sensors

For cooling towers, you need to choose the right cooling tower pH sensor to match your Lakewood Controller. There are some subtle differences that will prevent compatibility problems.

For a standard Cooling Tower pH:

  • If you are using a Model 1520e pH controller, you want our 1240472 pH sensor with it’s its PVC body, BNC connector, and 15′ of cable length.

Lakewood Instruments pH sensor

  • If you are using a Model 1575e or NexSys controller, you want our 1269422 pH sensor with the same PVC body but a SMB connector and 10′ cable length.

For a cooling tower, condensate, or waste application pH sensor for which you want to be specific about the type of glass on the sensor itself, we offer 520 series (BNC connector) and 522 series sensors (SMB connector), which have the options of:

pH Sensor Glass:

  • standard
  • dome glass
  • high sodium glass
  • pure water glass

pH Sensor Body Materials:

  • PVC
  • 316 SS with optional 10″, 18″ or 48″ body

pH Sensor Fitment:

  • Compression Fitting
  • Retractable Ball Valve

If you need a new pH sensor, we have just the right sensor glass, connectors, cables, transmitters, body material, etc. for your application.
