Swimming pool controllers with Cloud connectivity 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 disinfectant testing are done together for efficient disinfection and control. The efficacy of sanitisers, such as chlorine, depends on a controlled pH value. The ORP value is the most consistent indicator of the sanitising effectiveness of the pool or water treatment. Typically, 650750mV at 7.2pH indicates proper water treatment. The 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. Multiple registered devices may be connected. As your instrument measures and controls your process, measurements, trends, history, device settings, alarms and messages are transmitted to your “Dashboard”. A secondary user may also be added to your device account to monitor
and administrative security measures to reduce risks of loss or misuse.
The Hanna Instruments BL12X swimming pool controllers are automatic systems, specially designed to measure and control pH and free-chlorine levels
Automatic proportional pump control BL122 and BL123 feature 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 the pumps are dosing as a percentage of the deviation from the set point. A large body of water will use a small proportional band; having a small band (e.g. 0.1pH) will ensure the pumps are dosing more often when the reading is close to the set point. For smaller bodies of water, it is more useful to set a larger proportional band (e.g.,1.0pH); when the reading is close to the set point, the amount of time the dosing pump is on is minimal to avoid large swings of pH or ORP.

Analytical Reporter | Issue 4 | 2021
launch of the Ohaus Navigator High Resolution models. A balance designed to be durable enough for the most intense lab and industrial environments, versatile and intuitive enough for everyday workloads, and affordable enough to be accessible to everyone is not something that comes around often. Ruggedly constructed, the Navigator can take on a diverse range of weighing applications - providing precise measurements and durability while
doing so. The newly expanded series boasts stunningly fast stabilisation - so results are delivered quickly and accurately every time. Improved user interface and an easy-toread LCD display ensure there is no learning curve, and nothing standing between the user and their valuable and necessary data. The Navigator series is built to withstand anything a rigorous laboratory or warehouse can throw at it, and it works even harder to protect its users and their samples. Improved safety measures such as a revamped overload protection system that can handle loads up to four times the rated capacity and a corrosion-resistant
stainless steel pan take risk out of the equation. You get advanced results with everyday ease – the Navigator line is also priced to deliver industrial strength weighing at a cost that is accessible and affordable for all workplaces.
