VISOCOLOR® ECO Chlorine 2: Colorimetric determination of free and total chlorine. Features/ Specificatons: • At a pH value of 5 - 6 free chlorine reacts with N,N-diethyl-1,4-phenylene diamine (DPD) to form a red-violet dye. • In the presence of iodide ions the content of total chlorine can be determined, too. (Reaction basis according to DIN EN ISO 7393 G4-2) • 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. • Type: colorimetric test kit • Range: <0.1 · 0.1 · 0.2 · 0.3 · 0.4 · 0.6 · 0.9 · 1.2 · 2.0 mg/l Cl2 • Sufficient for: 150 determinations • Shelf life at least: 1.5 years • Sea water suitability: yes • Detectable with PF-12: yes Note: • When measuring the chlorine content in swimming pools it is recommended to check the pH value as well. • For this purpose we supply combination test kits VISOCOLOR® ECO Swimming pool.
