Bartovation Chlorine Test Paper, 0-200 ppm

The Chlorine Test Paper is an affordable and dependable way to measure the concentration of free available chlorine in sanitizing solutions. It comes in a pocket-sized, lightweight vial with a color chart protected by a splash-proof plastic covering. Each vial contains 100 strips, and the color chart block is set at 10, 50, 100, and 200 ppm. This test is perfect for testing chlorine sanitizers in three-compartment sinks and avoiding hefty Board of Health fines. It can also be used to test bleach-based sanitizers to kill bacteria, viruses, and fungi that may be transmitted on combs and scissors in barber shops and hair salons.

The chlorine test paper measures total chlorine available from 0-200ppm and gives results in seconds. The total available chlorine is the sum of free available chlorine and the combined available chlorine. This test is commonly used to check the strength of solutions used to sanitize surfaces, such as in the restaurant industry. Bleach is usually used to generate the available chlorine and should be diluted before use. It works best in the pH range of 5-7.

Dry fingers remove a strip from the vial to use the chlorine test paper. Dip the test strip into the solution to be tested without agitating it. Then, drag the strip and compare it to the color chart immediately. Note that the strip will darken over time, so it's best to compare it to the color chart as directed. Also, the color will be darker if two strips are stuck together. Lastly, laying the strip against the vial when comparing it to the color chart will also darken the color. The color chart was created by holding a strip next to the vial.

If you believe that the solution contains chlorine, but the test strip is white after dipping, you may see 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, the strip will quickly turn white instead of developing a purple color. 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.
