The ColorQ® 2x TesTabs® PRO 9 handheld pool and spa photometer directly measures nine tests that includes Free Chlorine (DPD), Total Chlorine (DPD), Bromine (DPD), pH, Alkalinity, Calcium Hardness, Cyanuric Acid, Iron and Copper. The photometer is easy to use and includes 100 instrument grade TesTabs® tablet reagents per test factor packaged in blister-style foil. The user dispenses each tablet into a ColorQ® 2x test tube by pressing the tablet through the foil. This eliminates the need to manually tear open a foil packet and carefully dispense the tablet. As a bonus, the ColorQ® 2x TesTabs® PRO 9 photometer can also measure 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 user friendly photometer, testing reagents, Pool Manager Handbook, Saturation Index Calculator and photo-diagrammatic instructions are packaged in a rugged carrying case for on-site testing.
