This is a single strip of 10 LaMotte DPD #1 Rapid Dissolve test tablets. 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.
A DPD #1 Rapid tablet will quickly reveal the precise level of Free Chlorine. (Note: Levels in excess of 10 ppm may bleach out any DPD test method.)
These are used with Lamotte chlorine comparators and colorimeters, specifically the Dipcell and Pool Manager Series Kits.
