Order Add to comparison

The Hach CN-67 kit contains all the necessary reagents and accessories for determining the concentration of free / total chlorine and pH in a water sample. Excellent for maintaining proper disinfectant levels in swimming pools and protecting systems from corrosion.

Includes: five reagents, two color discs, a color comparator box, two examination tubes, instructions and a carrying case.


Description

Description

The kit is designed to control chlorine and pH in pools and spas to maintain a safe bathing environment and protect against corrosion. Step-by-step instructions for each assay are described in the instructions included with the set.

Number of tests: 300
PH range: 6.6 - 8.4 units; method Phenol red
Free / total chlorine range: 0 - 3.4 mg/L Cl2; DPD method

Chlorine

Analyze samples immediately after collection. Undissolved reagent will not affect the accuracy of the test. When determining the concentration of free chlorine, read the result immediately after adding the reagent to prevent the influence of monochloramine. If the sample contains 3.0 mg/L of monochloramine, the free chlorine result is increased by 0.1 mg L every minute.

pH

Chlorine in a concentration of more than 15 mg/L interferes with the pH test. To remove chlorine from a sample, add 1 drop of 0.1 N sodium thiosulfate solution (sold separately) to 25 mL of the sample and mix. Use this dechlorinated sample in your test procedure. Sodium thiosulfate removes a maximum of 10 mg/L chlorine from the sample.
