Chlorine Test Kits

Free, combined and total chlorine may be determined using DPD with either colorimetric or titrimetric methods. These determinations are generally limited to concentrations of 0-10ppm, although the FAS titration can test higher concentrations with the addition of more DPD indicator. Higher concentrations require the iodometric titration, whereby the sample is acidified and iodide is added, which is oxidized by chlorine to iodine and is titrated with a standard Thiosulfate solution.

Comparators Method
Octet Comparator and Octa-Slide

The Octet Comparator and Octa-Slide contain eight color standards with built-in filters which eliminate optical distortion. The color standards in the Octet Comparator are arranged so that the sample can be compared to four standards at once. In the Octa-Slide, the standards are placed in a bar so that they can be compared to the sample individually.

Direct Reading Titrator Method
Direct Reading Titrator

The Direct Reading Titrator is a 1.0 mL microburet calibrated to allow direct reading of the test result. Each Titrator has a specific range, but may be refilled to test higher concentrations.

Dropper Bottle Method
Dropper Bottle

 The dropper bottle test uses bottle tips which deliver a consistent standard drop size to add titrant to the sample. As with the drop count test, the number of drops used to complete the reaction is multiplied by a given equivalence factor to determine the concentration.
