Designed to maintain constant pH and disinfectant levels in swimming pools, hot tubs, and spas, the BL122, and BL123 pH and ORP controller offers the added benefit of allowing remote connection and access to devices via the Hanna Cloud web app.
- Keep track from anywhere with Hanna Cloud connectivity.
- Inline or panel mounted models.
- Built-in datalogger for compliance monitoring
Peristaltic Chemical Feed Pumps
Equipped with two peristaltic dosing pumps with replaceable chemical resistant tubing that are proportionally controlled with adjustable flow rates.
Automatic Proportional Pump Control
Adjust the proportional band based on the sensitivity of your process to chemical addition, finetuning the amount of time that the pumps are dosing.
Adjustable Flow Rate
The dosing pump flow rate is adjustable from 0.5 to 3.5L/h, allowing for better control in maintaining a desired set point.
Connectivity
Transfer data to a PC using a flash drive and the USB port or connect via the Ethernet Port to the Hanna Cloud.
Hold Input
Connect a flow switch so that when there is no flow or no power applied to the recirculation pump, the hold circuit will disable the dosing pumps to prevent any dosing when there is no movement of water in the system.
BL123 Analog Outputs
The BL123 pH and ORP controller offers three 4-20 mA outputs that can be disabled or connected to an external recording device. Each of the three measured parameters (pH, ORP, and temperature) can be assigned to an analog output.
Programmable Alarm System
Automatic Logging
GLP
Password Protected
3 Display Modes
Keep Track Anywhere with Hanna Cloud Connectivity
Hanna Cloud is a web-based application that connects you to measurement devices such as the BL122 and BL123. Measurements and data storage are accessible from your PC, tablet or phone. Measurements, trends, history, device settings, alarms, and messages are transmitted to your “Dashboard” as your instrument measures and controls your process.
