The Waterproof Bluetooth® ColorQ® 2x PRO 7 handheld pool and spa professional photometer directly measures Free Chlorine (DPD), Total Chlorine (DPD), Bromine (DPD), pH, Alkalinity, Calcium Hardness and Cyanuric Acid (Stabilizer) directly on a digital display. The handheld meter is easy to use and features economical liquid reagents that measure 144 tests per test factor for Free Chlorine, Total Chlorine (Bromine) and pH. The Alkalinity, Calcium Hardness and Cyanuric Acid tests are measured by using the TesTabs® tablet method and includes 100 tablets for each test. The ColorQ® 2x eliminates the need to visually determine slight color variations, thus taking the guesswork out of poolside water analysis. The photometer, testing reagents and photo-diagrammatic instructions are packaged in a convenient carrying case for on-site testing.
