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 Instrument Grade will quickly reveal the precise level of Free Chlorine. (Note: Levels in excess of 10 ppm may bleach out any DPD test method.)

For use with Lamotte ColorQ Pro 7 and Pro 11 Digital Photometer Kits.
