The FAS-DPD Commercial 7 Test Kit was designed for public pool operators and commercial service professionals.

 

The pool analyst can measure Free and Total Chlorine levels in 0.2 or 0.5 ppm increments over a wide range by adding Chlorine Titrant that creates a clear endpoint color reaction. The Bromine test is measured by multiplying the Free Chlorine results by 2.25. The pH test is measured by adding just 5 drops of pH indicator to a 10 mL test tube then comparing the color to a pH Octa-Slide color bar with measurements from 6.8 to 8.2 in 0.2 pH increments. Along with the pH test Acid and Base Demand tests are included with tables to help adjust pH to the ideal range. The Alkalinity test employs a simple drop count method with 1 drop equal to 10 ppm once a red endpoint color change occurs. The Calcium Hardness test is a drop count method with 1 drop equal to 20 ppm at a blue endpoint color change. The Cyanuric Acid test uses a rapid dissolving tablet that develops a cloudy precipitate with results measured by the disappearing dot method.

 

The kit includes: The Pool Manager Water Quality Handbook, which has information on water balance, sanitizers, testing and treatment charts. A Saturation Index Calculator is added to each kit with diagrammed instructions in the lid of a sturdy blow-molded case.
