Advantages of DPD Test Kits

DPD Test Kits test for the level of disinfectant present (free chlorine) in your pool water with a high degree of accuracy. Many of the kits include tests for pH and other factors.

Professional Color-Matching Kits

Many test kits designed for professionals use the color-matching or drop-count titrations for straightforward answers. These kits typically use 2 ounce or tablet reagents and cover a variety of factors.

Ideal Alkalinity/pH Levels

Alkalinity levels should be between 80 and 120 parts per million (ppm). And our pH levels should be between 7.2 and 7.8 ppm.

Product Information


This is a Service Complete Kit for Chlorie/Bromine, pH, Alkalinity, Hardness, and CYA (DPD Low-Range) with 2 ounce bottles.
