Lakewood Model 1520/30e pH or ORP Water Treatment Controller

The Model 1520/30e uses the latest in microprocessor capability, giving the user a high level of application flexibility in pH or ORP control. The user in the field can configure this controller to operate as a pH or an ORP controller. A large illuminated graphics screen, multiple inputs, and very easy setup characterize this new technology. Water meters, sensors and plumbing assemblies are purchased separately.


  • Use this Controller for Cooling towers, Process, Wastewater, and Condensate systems.

  • Removable power cord and receptacles for simple conduit installations.

  • Scheduled feed, which can use three relays for biocides or other chemicals.

  • Two (2) water meter inputs, two (2) drum switch inputs, pH or ORP input, flow switch input, and 4-20 mA output are all standard features.

  • Designed with a single circuit board for better reliability and lower cost.

  • Large open shallow enclosure for easy wiring.

  • Heavy-duty stainless steel domed numeric keypad and illuminated graphical display allow for quick and easy programming. Steel domed switches improve the tactile sensing and life expectancy of the keypad.

  • LED indicators for power, alarm and relay status.


  • Easy to program, the Model 1520/30e Controller menu is just like the Lakewood 1575e controller.

  • Controller can be removed from a cooling tower and be placed in another type of application when used with the appropriate pH or ORP sensor.

  • Single circuit board design improves reliability.

  • No add-on options. 4-20 mA output and biocide features are standard.
