Swimming Pool & Spa Controller - BL122

Swimming Pool & Spa Controller - BL122

Automate your pool maintenance with the BL122. Confidently control pH and free chlorine levels in your swimming pool or spa, and have 24/7 remote access to measured data via cloud connectivity.

BL122/BL123 Swimming Pool Controller

 

Multiple Configurations

The BL122 Swimming Pool Controller is available two configurations. The in-line model allows for direct installation of the probe and chemical injection fittings into existing piping. A panel mounted version with a bypass flow cell allows for calibration and maintenance of the probe without having to shut down the recirculation pump.

 

Automatic Logging

The readings for each parameter are automatically logged every 10 seconds. A new log is started each time the instrument is calibrated or at the start of a new day. Logged data include pH, ORP, and temperature values, last calibration data, setup configuration, and any event data.

 

Three Display Modes

The versatile display of the BL122 allows for three display modes. The LCD can display all three parameters at one time, a 3-second cycle of single parameters, or a real-time plot screen with options for parameter selection, zooming, and log recall.

Peristaltic Dosing System

The BL122 is equipped with two peristaltic dosing pumps with replaceable chemical resistant tubing which resists the buildup of chlorine gas seen when using a diaphragm pump.

 

Proportional Pump Control

The BL122 features proportionally controlled dosing pumps. Based on the sensitivity of the process to chemical addition, these controllers allow the user to adjust a proportional band. This setting determines the amount of time that the pumps are dosing as a percentage of the deviation from the set point allowing for very fine control in maintaining the desired set point.

 

Adjustable Flow Rate

The flow rate from the dosing pumps is adjustable from 0.5 to 3.5L/h to allow for better control in maintaining a desired set point.

 

ORP Dosing Consent

The BL122 utilizes a dosing consent feature that will not dose chlorine until the pH value is first corrected preventing chemical waste and avoiding a higher than necessary chlorine concentration.



Application Specific Probe

 

 

Monitor from Anywhere

Connect your BL122 controller to a local network using the ethernet port. All measurements and main events are sent to Hanna Cloud through the ethernet connection where they are viewable for all connected devices. With ethernet capaility and the Hanna Cloud, you can use the Internet to manage your pool from anywhere.

 

Programmable Alarm System

This pool controller allows you to enable or disable the low and high level of alarms for all parameters. When an alarm is activated, all dosing will stop. The alarm system also offers overdosing protection if the value is not corrected within a specified time interval then the meter will go into alarm status. Enable remote notifications via the Hanna Cloud.

 

Multifaceted Display

The versatile display of the BL122 allows for three screen modes. The LCD can display all three parameters at one time, a 3-second cycle of single parameters, or a real-time plot screen with options for parameter selection, zooming, and log recall. An on-screen icon indicates that the BL122 is connected remotely.

HI1036-1802 combined electrode

 

Multiparameter Digital pH, ORP, Temperature Probe - HI1036-1802

pH and disinfectant testings are made using the HI1036-1802 combined electrode installed inline or in flow cell. The HI1036-1802 with the BL122 Pool Controller helps to promote the health and safety of pool and spa water.

 

Potential Matching Pin

This probe incorporates a potential matching pin to prevent ground loop effects from causing erratic readings and damage to the system.

 

Specialized Design

The pH glass has been chosen to produce stable quick equilibration even in low conductivity waters. The ORP sensing surface is a large smooth surfaced platinum band that encircles the circumference of the temperature probe.

 

Digital Signal

The probe converts these measurements to a digital signal to eliminate noise and static due to high impedance signals carried by cable.
