ORP Sensors for Cooling Towers

The right pH sensors for your cooling tower, condensate or waste application.
Lakewood Instruments ORP Sensor

Biocides are more and more important in a world of legionella and the awareness of how biological fouling reduces heat transfer. If you are using ORP sensors to help automate your system, Lakewood has the right sensor for you.

Time for a new ORP sensor? Take advantage of our 45+ years of experience to get what you need.

For a standard Cooling Tower ORP:

  • If you are using a Model 1530e ORP controller, you want our 1240473 ORP sensor with its PVC body, BNC connector, and 15′ of cable length.
  • If you are using a Model 1575e or NexSys controller, you want our 1269423 ORP sensor with the same PVC body but an 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 530 series (BNC connector) and 532 series sensors (SMB connector), which have the options of:

Body Materials:

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


  • Compression Fitting
  • Retractable Ball Valve

Let’s see: two body materials, three mounting options, two electrical connectors – that can be confusing. Call us and we will simplify the process so you get exactly what you need!
