BL-132-20 SWIMMING POOL CONTROLLER WITH EXTERNAL DOSING ,FLOW CELL AND REMOTE CLOUD CONNECTIVITY

The BL132 swimming pool controllers are automatic systems, specially designed to measure and control pH and free-chlorine levels.

The chlorine level is measured based on the ORP or REDOX principle. An increase in the ORP value correlates with an increase in the free-chlorine level. pH and ORP testing are done together for efficient disinfection and control. The efficacy of sanitizers, such as chlorine, depends on a controlled pH value. The ORP value is the most consistent indicator of the sanitizing effectiveness of the pool or spa. Typically, 650-750 mV at 7.2 pH indicates proper water treatment.

The controllers offer remote access and visualizing of measured data via Cloud connectivity. All measurements and main events are sent to Hanna Cloud through the Ethernet connection.  

BL-132 controllers paired with the HI1036-18XX digital probe. The probe incorporates pH, ORP and temperature sensors along with a matching pin. It was specially designed to detect a broken electrode based on a shifted zero potential value, around 4 pH. The HI1036-18XX uses an Ag/AgCl reference with 3.5 M KCl. The ORP values are referenced to it. Measurement data stored on the probe is transferred to the controller via a digital connection; thus eliminating noise and static due to high impedance signals carried by the cable. 

Multiple Configurations

BL132 swimming pool controllers are available in two configurations:

• In-line, for direct probe installation and chemical injection fittings into existing piping

• Flow cell, for calibration and probe maintenance without having to shut down the recirculation pump.

For compliance monitoring, each of the BL132 has a built-in datalogger. Measurement reading intervals can be set at 30s/1m/5m/15m/30m/1h, with a new log starting new each day or when the instrument is calibrated. Logged data include pH, ORP, and temperature values, last calibration data, setup configuration, and any event data.

Main Features

• Two built-in peristaltic dosing pumps with Proportional control

• Manual control for pump priming • Overfeed protection using overtime safety timer

• Resumes dosing on restart in case of power failure

• Level input to stop control without reagents

• Interlocked pH-ORP control (i.e. ORP control only runs when the pH set point has been reached)

• External dosing - The controller has 2 relays that can be used to control larger external dispensing pumps, allowing the BL132 to be used in larger pools.

• Air temperature sensor - Allows triggering an alarm if the air temperature is cold enough that there is a risk of water freezing in the pipes (e.g. hot tubs in winter with the circulation pump off)

• Bidirectional control - Use the Hanna Cloud to update settings on the controller

• User selectable logging interval - As pool settings normally do not change that quickly, minimize data management by choosing from a wide selection of logging intervals 

• Multicolored LED indicators for dosing, meter status and service

• Real-time graph display

• Programmable alarms

• Password protection  

Three Display Modes

The versatile display of these controllers (BL131 and BL132 screens shown) 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. 

BL132 – Keep Track Anywhere with Hanna Cloud Connectivity

Hanna Cloud is a web-based application that connects you to the BL132. Measurements and data storage are accessible from your PC, tablet, or phone. Multiple devices can be registered to a single Hanna Cloud account.

Measurements, trends, history, device settings, alarms and messages are transmitted to your “Dashboard” as your instrument measures and controls your process.

Multiple secondary users may also be added to your device account to monitor measurements and receive notifications from your controller.

Hanna Cloud incorporates security for your personal information. We protect your information using technical and administrative security measures to reduce risks of loss or misuse. These include (but are not limited to), a secured connection, device identity registration, and password encryption.

Primary Applications:

Swimming pools, hot tubs and spas.
