2. Add one Free Chlorine DPD1R Tablet to the small chamber next to the CL DPD colors.
3. Add one Phenol Red Tablet to the small chamber next to the pH colors.
4. Cap and invert to mix. Match sample colors to the color standards and record results. Rinse promptly after use.

Important Tips

• Take water sample from a depth of about 16 inches below the water surface. Never test immediately after adding pool/spa chemicals.
• When adding tablet reagents, just push the tablet through the foil package into the test chamber.
• Read results immediately.
• Read your test results in natural daylight but away from direct sunlight. To read, hold Dip cell comparator at arms length above the horizon.
• Rinse the DipCell comparator thoroughly before and after testing.
• Store kit in a cool dry place away from sunlight.
• Levels of chlorine above 10 ppm can cause bleaching of the DPD reaction.
