Lakewood 150 Water Treatment Controller

The Model 150 boiler conductivity controller uses the latest in microprocessor capability, giving the user a high level of application flexibility. Multiple inputs and very easy setup characterize this new technology. This water treatment controller can be used in the Continuous Sample, Sample/Cycle, or Sample/Hold modes to control the boiler water conductivity. This flexibility gives you the option that best fits your preferences and your system’s requirements.

Make sure you order the controller with the conductivity sensor, plumbing kit and motorized blowdown valve for a complete system.
