The photometer directly measures nine tests that include Free Chlorine (DPD), Total Chlorine (DPD), Bromine (DPD), pH, Alkalinity, Calcium Hardness, Cyanuric Acid, Copper and Iron directly on a digital display. The handheld meter is easy to use and features economical liquid reagents that measure 288 tests per 60 mL size bottle for Free Chlorine, Total Chlorine, Bromine, and pH. The Alkalinity, Calcium Hardness, Cyanuric Acid, Copper and Iron test are measured by using one TesTabs® tablet per test with 100 tablets included with the kit. As a bonus, the ColorQ® 2x PRO 9-PLUS photometer can also test Biguanide (Order Code 3919-G) and Biguanide Shock (Order Code 6930A-J) with optional reagents sold separately. The ColorQ® 2x eliminates the need to visually determine slight colour variations or use look-up tables, thus taking the guesswork out of poolside water analysis. The ColorQ® 2x PRO 9-PLUS photometer, Pool Manager Handbook, Saturation Index Calculator, instructions and reagents are packaged in a rugged carrying case for on-site testing.
