Before starting analysis:

  • Use sunlight or lamp as the source of light to match the color with the color comparator box.

Test procedure

Fill two tubes to the first line with sample. Place the first tube into the left opening of the color comparator box. Add the content of DPD Total Chlorine Powder Pillow to the second tube and swirl to mix. The pink color develops as the result of the reaction. Wait 3 minutes and read the testing results within 6 minutes. Install the second tube into the color comparator box. Set the color comparator box in front of the light. Rotate the color disc to match the color. Analyze testing results displayed in mg/L in the scale window.
