BL-136-20110 Salt Pool Controller with Chlorine Generator 10 g/h Output, pH Control and Remote Cloud Connectivity
The Hanna Instruments BL-136 Salt Swimming Pool Controller and BL130-7X0 Salt Chlorinator is designed to automate and control free chlorine, pH, and disinfection levels in saltwater swimming pools.
The system uses electrolysis to convert dissolved salt (sodium chloride) in the water into hypochlorous acid (HOCl) to sanitize the pool.
Hypochlorous acid (HOCl) is the form of chlorine most effective at destroying pathogens. HOCl is formed in its highest concentrations between pH 7.2 and pH 7.4, and serves as a disinfectant, oxidiser, and has residual protection.
The controller displays the continuous measurements of pH / ORP (redox), free chlorine values, as well as water and air temperatures, and the salt level of the pool water while water is circulated past the HI-1038-2802 pH / ORP probe and the HI-1040-1801 chlorine probe.
The BL136 Salt Swimming Pool Controller automates chlorine generation and acid or base additions to configured setpoints or time periods. Chlorine is generated by the BL130-7X0 chlorinator in a flowing system that requires the pool’s recirculation pump to be active.
In automatic mode, chlorine generation only starts after the pH setpoint has been reached. Acid or base additions use the integrated peristaltic pump with proportional control to prevent overdosing.

Ethernet port for Hanna Cloud connectivity (BL136 only)
The BL-136 Salt Swimming Pool Controller can connect to Hanna Cloud, a web-based application. The BL-136 connects to the internet using an Ethernet connection.
Measurements, trends, history, device settings (including remote hold), alarms, and messages are transmitted to the user’s “Dashboard”, as the instrument controls the process.
The BL-136 supports bidirectional support of settings.
Sanitation monitoring and control
The BL-136 system relies on a two-tier approach for automated chlorine management and water-sanitation monitoring.
The HI-1040-1801 membrane-covered chlorine electrode measures the actual concentration of free chlorine (mg/L) in the pool water and is used for primary control. This probe contains a chlorine sensor for real-time monitoring of chlorine levels.
The HI-1038-2802 pH sensor is highly effective at measuring pool- water alkalinity thus monitoring the real-time disinfection efficacy. This probe contains pH, ORP, and temperature sensors as well as reference and salinity electrodes in a single body. The ORP (redox) sensor is gold. The salinity pins are titanium, and the probe body is PVDF.
The system uses the pH sensor to compensate the signal, ensuring that even if the pH drifts slightly, the chlorine reading remains accurate.
BL-130-7X0 chlorinator control
The chlorinator control can automatically regulate chlorine production using chlorine (Cl) setpoints and measurements as well as fixed chlorine production. It features a Fixed Mode, Pool Startup Mode, a Boost and Scheduled Boost Mode, and Pool Cover detection.
- Fixed mode - A “Fixed” mode may be set for proportional chlorine generation. The proportional generation method varies the voltage and amperage for the chlorine generation percentage (%) and continuously produces chlorine. The “Fixed” mode, when Extend Cell option is enabled, runs the chlorine generator intermittently at 100% power (with off periods).
- Pool startup mode - “Pool Startup” mode enables automatic, independent chemical dosing based on pH and chlorine setpoints for up to 12 hours.
- Boost & scheduled boost mode - The “Boost Chlorination” feature provides maximum chlorine production for configured amount of time. It then switches back to previous setting i.e. AUTO or FIXED. Users can schedule 100% output for specific times on the specified days of the week to align with heavy usage.
- Pool cover detection - The chlorine production is decreased if a pool cover it detected and the cover alarm is triggered.

Peristaltic chemical feed pump
These controllers are equipped with a peristaltic dosing pump with replaceable chemical resistant tubing that is proportionally controlled with adjustable flow rates.
Multi-coloured LED Indicators
The controllers offer multiple LED indicators for status, servicing, and pump operation. The STATUS LED changes colour based on operational state; a green LED means the water is within the desired parameter ranges, a yellow LED means that the controller needs attention, and a red LED identifies a problem in the system such as high/low alarms. The SERVICE LED indicates attention is required by a service technician.
Automatic proportional pump control
BL-136 features a proportionally controlled dosing pump. The user can set the proportional band based on the sensitivity of the process.
This setting determines the amount of time that the pumps are dosing as a percentage of the deviation from the set point. For example, a large body of water will use a small proportional band; having a small band (e.g., 0.1 pH) will ensure the pumps are dosing more often when the reading is close to the set point. For smaller bodies of water such as hot tubs or spas, it is more useful to set a larger proportional band (e.g., 1.0 pH); when the reading is close to the set point, the amount of time that the dosing pump is on is minimal to avoid large swings of pH or ORP. This valuable feature allows for very fine control in maintaining the desired set point.
Adjustable flow rate
The dosing pump flow rate is adjustable from 0.5 to 3.5 L/h (0.13 to 0.92 gal/h). Larger bodies of water require more chemical to be dosed than small bodies since it takes more chemical to see a change in the reading. The adjustable flow rate, like the proportional band, allows for better control in maintaining a desired set point.
Automatic logging
Measurement readings can be set at 30s/1m/5m/15m/30m/1h intervals. A new log is started each time the instrument is calibrated when a setting is changed, or when a log becomes full.
Logged data includes pH, ORP, salinity, chlorine, air and water temperature values, last calibration data, setup configuration, and any event data. Logs can be viewed on display in standard or plot mode and can be exported to USB flash drive in .CSV format.

GLP
Good Laboratory Practice (GLP) refers to a quality control function used to ensure uniformity of probe calibrations and measurements.
GLP stores chlorine, pH, ORP, and salinity calibration information such as calibration points, date and time, and pH buffers used.
Alarm system
Programmable alarm system
These controllers allow users to enable or disable the low and high level of alarms for all parameters: pH, ORP (mV), chlorine, salinity, and temperature. When an alarm is activated, all dosing will stop. The alarm system also offers overdosing protection in that if the value is not corrected within a specified time interval, then the meter will go into alarm status.
Hold input
It is possible to connect a flow switch mounted in-line or a mechanical relay that is connected to the recirculation pump power source to the hold input of these controllers. With no flow or when no power is applied to the recirculation pump, the hold circuit will disable the dosing pumps. This will prevent any dosing of chemical when there is no movement of water in the system.
Safety features
- The flow control immediately stops continued chemical dosing when the flow through the chlorinator cell is stopped
- Chlorinator safety sensor - Monitors for gas entrapments, lack of water, low temperature, low salt
- pH safety devices - Overtime timers provide overfeed protection, crucial for shutting down acid or base feeding if pH sensor fails or recirculation system stops
- Programmable alarms
- Password protection - Restricted access to calibration, setup, and review of logged data
Display modes
The versatile display of these controllers allows for multiple display modes. The LCD can display all parameters, single parameter, chlorinator (cell status), or 24-hour plot screen with options for parameter selection and additional details.
