Description
The VISOCOLOR® alpha Chlorine Test Kit is for the colorimetric determination of free chlorine.
The addition of chlorine to swimming pools, water reservoirs and water mains is an approved procedure to rid the water of germs. With the correct dose harmful microorganisms are destroyed, many impurities removed and the growth of algae is prevented. However it is imperative that the chlorine content is regularly checked, since excessive chlorine not only impairs the smell and taste of the water but can be hazardous.
One distinguishes between free chlorine and bound chlorine (chloroamines); the sum of both is called total chlorine.
The determination of free chlorine includes the concentrations of bromine, bromoamine, chloroamine, iodine and in part chlorine dioxide.
1,0 mg/L Cl2 = 2,3 mg/L Br2 = 3,6 mg/L I2
Suitable for testing sea water.
