Lakewood Instruments Conductivity Controller

Model 3175 Boiler and Cooling Tower Water Treatment Controller

Overview

• Accurately controls boiler and cooling tower conductivity. A standard secondary input may be used to control ORP or pH.
• Easy to program with an intuitive menu to configure for either cooling tower, boiler, or condensate applications with appropriate conductivity sensors.
• Larger 7” responsive touch screen display for quicker setup compared to using a keypad.
• Updated processor for modern connectivity and datalogging.
• Email alarm notifications.
• Reliable circuitry that has been proven for two decades to accurately control your water chemistry.
• User-selected relay options for a high level of application flexibility.
• Configure relays to your preference – for setpoint control, based on water meter, percent of blowdown or percent of time.
• Up to 12 scheduled feeds can be configured for excellent control of your system.
• Affordably priced between our Model 1575e and NexSys water treatment control systems.
