BL122 and BL123 are designed to maintain constant pH and ORP (disinfectant) levels in swimming pools, hot tubs, and spas and offer the added benefit of allowing remote connection and access to devices via the Hanna Cloud web app. Available in two configurations, the basic version allows for direct installation of probe and chemical injection fittings into existing piping. Also available is a panel mounted version with a bypass flow cell that allows for calibration and maintenance of the probe without having to shut down the re-circulation pump.
