Chlorine Products
Chlorine is a chemical element and halogen. It is almost exclusively manufactured using electrolysis (chloralkali process) and is used for a wide variety of applications.
Additionally, chlorine is widely used for disinfection of swimming pools, water mains, and water reservoirs. Electroplaters use chlorine for the detoxification of cyanide-containing waste. Regular monitoring of chlorine level is essential as excessive chlorine not only impairs the smell and taste of water but can also be hazardous.
VISOCOLOR® Powder Pillows are photometric tests that combine easiest dosing of reagents with photometric precision.
