Description of DPD 3 Test Tabs - Strip of 10 Tabs

The DPD tablet is the most widely used test for determining Free and Combined Chlorine in pool water. Establishing a Free Chlorine residual is the most important step toward protection of bather health.

The DPD #3 Rapid tablet measures the level of Combined Chlorine. Combined Chlorine is a sanitizer that has reacted with impurities within the water and is, therefore, less capable of disinfecting pool water. It can cause eye irritation and a strong chlorine odor. To test for Combined Chlorine, simply add a DPD #3 Rapid tablet to the Free Chlorine water sample. A measurable increase in sample color indicates undesirable Combined Chlorine, which should be treated with a chlorine or oxygen-based shock treatment.
