Hanna Instruments BL122 and BL123 pH/ORP Controllers
Hanna Instruments’ BL122 and BL123 controllers are designed to maintain constant pH and disinfectant levels in swimming pools, hot tubs and spas, allowing remote connection and access to devices via the Hanna Cloud web app.
Using the Hanna Cloud app, measurements, trends, history, device settings, alarms and messages from multiple BL122 or BL123 controllers can be accessed via the ‘Dashboard’.
The controllers are available in two configurations: the basic version is an inline model that allows for direct installation of probe and chemical injection fittings into existing piping; the panel-mounted version with a bypass flow cell allows for calibration and maintenance of the probe without having to shut down the recirculation pump.
For compliance monitoring, BL122 and BL123 have a built-in datalogger, logging measurements every 10 s with a new log starting every day or when the instrument is calibrated. Logged data include pH, ORP and temperature values, last calibration data, set-up configuration and any event data. The BL123 model includes three 4–20 mA analog outputs to connect to an external datalogger.
