This Chlorine Test Paper measures total available chlorine from 0-200ppm, and give results in seconds. Total available chlorine is the sum of free available chlorine and the combined available chlorine. It is most often used to test the strength of solutions used to sanitize surfaces, for example, in the restaurant industry. In these types of applications, bleach is usually used to generate the available chlorine.
When using bleach as a cleaner, it must be diluted before use, and it will work best in the pH range of 5-7.
- Use dry fingers to remove a chlorine test paper strip from the vial.
- Dip the test strip into the solution to be tested, and do not agitate.
- Remove and compare to the color chart immediately.
NOTE: If you believe that the solution contains chlorine, but the test the strip is white after dipping, you may be seeing what is referred to as the “bleaching out effect.” At high concentrations of bleach, the available chlorine will overwhelm the indicators used in the strips. If this happens, instead of developing a purple color the strip will very quickly turn to white. The best indicator of this effect is the presence of a thin blue line on the strip separating the wet portion from the dry portion of the strip.
