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.
