Product Description
The BL122 Cloud Enabled Swimming Pool pH/ORP Controller with built-in dosing pumps enables intelligent pool water management by automating the control of pH and ORP (disinfectant) levels. Designed for swimming pools, hot tubs, and spas, this controller supports Hanna Cloud connectivity for remote operation and continuous monitoring through a web application.
- Enables remote connection, diagnostics, and logging via Hanna Cloud web app for convenient pool monitoring and compliance.
- Maintains optimal pH (0.00 to 14.00; ±0.05 pH) and precise ORP (±2000 mV; ±5 mV) using robust digital sensors.
- Built-in dosing pumps deliver proportional chemical feed controlled by set points, interlocks, and over-dosing timers.
- Features relay alarms for high/low readings, adjustable set points, and automatic event logging for critical process safety.
- Comprehensive measurement and data storage: 60 days of logging memory, automatic recording of pH, ORP, temperature, and operational events (alarms, power-failures, errors).
- Advanced probe (HI1036-18XX) integrates pH/ORP/temperature with matching pin digital interface: available in 2–20 m cable options.
- Full compatibility in both direct-pipe and panel/bypass-mounted installations, supporting calibration and maintenance without shutting down pool recirculation.
- Automatic pH buffer calibration (4.01, 7.01, 10.01), single-point process calibration, and integrated temperature compensation for measurement reliability.
- Environmentally robust operation: 0–50°C temperature range, up to 95% RH (non-condensing).
- 4–20 mA analog output signals (optional on BL123), USB connectivity, galvanic isolation, and digital/consent relay input for system integration.
- Compact design: 245 x 188 x 55 mm (73 mm with pumps), weight 1.7 kg (60 oz).
This pool controller is suited for resorts, commercial, hotel, and residential swimming pools requiring advanced automation and water safety compliance. Browse more advanced swimming pool and spa controllers on EnvMart for complete water management solutions.
