Supplied with our Digital Multiparameter pH/ORP/Temperature electrode (HI1306-1802). This electrode arrives with a matching pin that can detect a broken electrode. The matching pin also prevents ground loop effects from causing erratic readings and damage to the system
Designed with an easy-to-read, LCD screen with three display modes. Users can choose to view all 3 parameter measurements at once, one parameter reading at a time that rotates every 3 seconds, or a real-time plot graph
Equipped with a programmable alarm system for all 3 parameters including pH, ORP, and temperature. Choose to enable or disable alarms for when parameter levels are out of range. Once an alarm is activated, dosing will stop completely. Our Swimming Pool and Spa Controllers will also switch to alarm mode if the value is not adjusted within a specified timeframe to prevent overdosing
Built with multicolored LED indicators that visually signal the status of the controller and how it is functioning. Green shows when the parameters are within range, yellow means that attention is required, and red notifies users that there is a problem and that levels are not within range
These controllers allow for a connection to an optional level controller. This input is used to disable the dosing pumps when there is no chemical left in the reservoir tank

Our Swimming Pool and Spa Controllers (BL121 and BL123 only) have 3 analog outputs (4-20 MA) for pH, ORP, and temperature. Each analog output can be disabled or connected to an external recording device. Parameters can be assigned to an analog output where the current signal will adjust to be proportional to the measured value. For greater flexibility and better resolution, the analog output can be scaled and users can define any two points within a parameter range to correspond to the analog output span. This adjustment allows for better resolution for the desired range
Connect an inline flow switch or a mechanical relay to the recirculation pump power source. This holds the input of these Swimming Pool and Spa Controllers. If there is no flow or if the recirculation pump has no power, then the hold circuit will disable the dosing pumps. This prevents the dosing of chemicals when there is no movement of water in the system
The readings for each parameter are automatically logged every 10 seconds. A new log is created at the start of a new day or each time the controllers are calibrated. All necessary GLP (Good Laboratory Practice) data is stored including the values for each parameter, any event data, and calibration and setup configuration information
Export and transfer data using a USB Flash Drive and the USB-C port
Secure these controllers with password protection. Users can choose to restrict access and passwords can be enabled or disabled during set up
Available with our Swimming Pool and Spa Controllers (BL122 and BL123 only). These controllers can connect to the Hanna Cloud using a secure Ethernet connection for data viewing and tracking
