The meters have a user selectable set point and a visual LED alarm that is active when the reading is higher (for pH) or lower (for mV) than the set point. Also the instruments are supplied with a power plug for CO2 or ozone dosing. With each Smart controller, your system’s water will have the individual attention that it needs.
