Tablets DPD No1 for Free Chlorine

Tablets DPD No1 for Free Chlorine are precision-formulated test tablets designed to work with pool water testing kits based on the DPD (Diethyl-para-phenylene diamine) method. These tablets enable clear and reliable detection of free chlorine (Free Cl) — the active form of chlorine responsible for disinfecting swimming pool water by eliminating bacteria, algae, and other contaminants.

Maintaining proper free chlorine levels is essential for healthy, safe and comfortable pool water. Low chlorine can lead to cloudy water and microbial growth, while overly high levels can cause skin and eye irritation. With DPD No1 tablets, pool owners and professionals can easily monitor and adjust sanitizer levels to stay within optimal ranges. Suitable to use with all tablet based test kits. Not for photometers.

These tablets are ideal for use in both residential and commercial pools, spas, and water features, providing a consistent, repeatable color change that correlates with chlorine concentration when compared against a color chart or photometer.

Waterproof foil contains 10 tablets.
