Hanna Swimming Pool Controller with Built-in Dosing Pumps - BL120

The BL120 Swimming Pool Controller with Built-in Dosing Pumps, Model BL120, provides comprehensive water treatment management for swimming pools, hot tubs, and spas. It continuously monitors and regulates pH, ORP, and temperature to ensure safety and optimal disinfection. The controller supports both in-line direct piping installation and convenient panel mounting, with a bypass flow cell option for easy probe maintenance and calibration without stopping the pump.

• Continuous and precise measurement of pH (0.00 to 14.00), ORP (±2000 mV), and temperature (-5 to 105 °C).
• Accepts multi-parameter digital probe (HI1036-18XX) for simultaneous readings.
• Automatic calibration (two-point for pH buffer, single-point for process calibration) for reliable measurements.
• Proportional dosing control adjusts chemical feed based on setpoint and proportional bands, with overfeed protection timer for safety.
• USB connectivity for configuration and data logging.
• Alarm relays with programmable trigger points for high/low readings, disabling options, and event logging.
• Digital and analog outputs (4 to 20 mA, isolated up to 50 V) ensure seamless integration with dosing and safety systems.

Industrial, commercial, laboratory, and water treatment facilities benefit from its robust design, real-time data logging (60-day, 10-second interval), and full GLP compliance for pH/ORP. The controller features LED status indicators, overfeed alarms, and password protection for security. Applications include hotels, community pools, spas, water parks, and HVAC water circuit treatment.

Controller dimensions: 245 x 188 x 55 mm (73 mm with pumps) and weight 1.7 kg. Package includes BL120 controller, dosing pumps, cables, and probe with up to 20 m cable (model-specific HI1036-18XX).
