An instrument that determines the total alkaline substances dissolved in pool water. It typically accepts the input of various water chemistry readings and performs calculations to provide a final alkalinity reading. For instance, a user might input pH, calcium hardness, and stabilizer levels, and the device will then output the water’s overall alkalinity, usually expressed in parts per million (ppm).
Maintaining appropriate levels of this water quality parameter is critical for bather comfort and pool equipment longevity. Low levels can cause corrosion of pool surfaces and equipment, while high levels can lead to scaling and cloudy water. Historically, test kits relying on manual titration were used to measure this water quality aspect. This device automates and simplifies the process, providing a more precise reading and reducing the risk of human error.
