Chlorine is commonly used as a disinfectant to improve the water quality by removing harmful microorganisms. It is typically used in swimming pools and spas, and also in drinking water. It is essential to monitor the chlorine levels to ensure there is enough chlorine present for disinfection, and to control any adverse effects, such as taste, smell, and potential formation of harmful byproducts from reactions with organic matter in the water.


From Chemical Test Kits to portable and bench Photometers, Hanna provide a wide range of instruments suitable for testing of both free and total chlorine.
