HCK Colortest Total Chlorine

Measurement of the color intensity of the yellow complex formed by the reaction of chlorine with o-toluidine.

0,1 - 0,25 - 0,5 - 0,75 - 1,0 – 1,25 – 1,5 – 2 mg/l Cl2

350

potable, purified, wastewater, swimming pool and chlorinated water with few organic substances.

• 4 bottles of 25 ml reagent
• 1 syringe of 5 ml
• 2 test tubes of 20 ml with stopper
• 1 optical comparator
• 1 chromatic scale
• Instructions (English)

• The method is applicable for the measurement of total chlorine which, in the case of unpolluted water, free of interfering substances, corresponds to free chlorine.
• The concentration of o-toluidine in the reagent Chlorine A is lower than the limit required by EEC directive 67/548 to be considered hazardous.
• The optical comparator contained in the package allows the comparison of the color between two test tubes containing the same amount of water, so as to improve the accuracy of the result.
• HYDROCHECK kits (which can be purchased directly) allow to perform a variety of precise analyses at a very low cost per analysis. If accuracy is not mainly important and there are few analyses to be performed, it may be favorable to use DROPS kits, whose cost per package is considerably lower (to be purchased through resellers).
