How to Use Free and Total Chlorine Water Test
1. Dip one test strip into a 250 ml (1 cup, about 8 oz.) sample for ten (10) seconds, with constant back and forth motion that maximizes water flow through an indicator pad.
2. Remove and shake strip once, to remove excess water. Wait for fifteen (15) seconds.
3. Match the best color for Free Chlorine (end pad) , and Total Chlorine (pad closest to handle) to determine Parts Per Million (ppm) or mg/Liter concentration of chlorine and chloramines in your water sample.
Use coloring chart provided with the package. This is a Free Chlorine chart provided with the product:
If you find that your level of chlorine is 4.0 ppm (parts per million) or above, please dilute water sample (mix half tap water and half distilled water) and repeat a test, until you get a number in the range between 0.1 and 2.5. Then multiply your number by the number of times you had to dilute water.
Chloramine, which is also called "combined chlorine", is a chlorine combined with another chemical. Free Chlorine test will not show levels of combined chlorine (chloramines) in your drinking water. That's why we provide a dual test for Free and Total Chlorine.
