The Chlorine Test Paper measures total available chlorine from 0-200ppm, and give results in just seconds. Total available chlorine is the sum of free available chlorine and the combined available chlorine. Our chlorine test paper is most often used to test the strength of solutions used to sanitise surfaces, for example, in the restaurant industry. In these types of applications, bleach is usually used to generate the available chlorine.

Instructions
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 colour chart immediately.
NOTE: The strip will darken over time, so it is best to compare to the colour chart as directed. In addition, if two strips are stuck together, the colour will be darker. Lastly, if you lay the strip against the vial when comparing to the colour chart, it will also darken the colour. The colour chart was created by holding a strip in the air next to the vial.
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 colour 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.

The Low Level Chlorine test strip measures residual chlorine from 0-10ppm in increments of 0-0.5-1-3-5-10 in just seconds. This test strip detects residual levels of free chlorine. It is accurate within 5-10% of reading the colour scale. The strip can also be used to test for chlorine in drinking water if this is a concern, however, our Residual Chlorine test strip, which measures up to 5ppm, may be a better suited option for testing residual in drinking water.
