HCK Spectratest Total Chlorine

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

0,1 - 2,0 mg/l Cl2

350

o-toluidine

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

• 4 bottles of 25 ml reagent
• 2 plastic test tubes of 20 ml with stopper
• 2 test tubes of 16 mm optical glass with stopper
• 1 syringe of 5 ml
• 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 SPECTRATEST HYDROCHECK kits (which can be purchased directly) require the use of a photometer or spectrophotometer to perform many precise analyzes at a very low cost per analysis. HYDROCHECK MONOTEST kits are preferred because of their greater convenience and safety of use. The cost per analysis of MONOTEST kits is higher, but the analysis is very simple because the samples to be analyzed are introduced into optical glass tubes containing the pre-dosed reagents that can be used directly in the appropriate photometers. MONOTEST kits are recommended when there are few analyses to be performed. As for the photometer, it is preferable to use a spectrophotometer such as the Hydrocheck or Spectronic Genesys, since filter photometers give less reliable and precise results, as well as always requiring the construction of a calibration curve.
