As pH gets higher, however, the process slows down, and more of your chlorine is converted into the a weaker form of chlorine. The more acidic the water, the lower the pH and the higher the likelihood of corrosion. When the water contains pH levels that are higher than 8.0, its likely that theres isnt much hypochlorous acid in the solution, which makes it more difficult for amperometric sensors to identify free chlorine. There are two types of alkalinity tests, titration and colorimetric. Measuring free chlorine is mainly done for two reasons, which include dosage testing and monitoring chlorination compliance for different types of projects. It finally got to 5 today. The most common chemicals are Sodium Thiosulfate and Sodium Sulfite. (See TN46.) On the other hand, color-wheel test kits have a lack of standardization and calibration when compared to digital meters. However, there are a couple of drawbacks to using digital colorimeters, which include a high cost compared to other options as well as the need to calibrate the sensor with specific standards.
