Photometer directly measures seven pool & spa tests which includes Free Chlorine, Total Chlorine, Bromine, pH, Alkalinity, Calcium Hardness and Cyanuric Acid. The photometer is easy to use and includes 100 TesTabs® tablet reagents per test factor packaged in blister-style foil. The user dispenses each tablet into a ColorQ 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. The user friendly photometer, testing reagents and photo-diagrammatic multilingual instructions (English, Spanish, French) are packaged in a convenient carrying case.
