Maintaining safe pool/spa water is an important responsibility. Therefore, precise test results are essential when checking the water quality of pools and spas. Taylor’s 2000 Series is designed for the kind of comprehensive, routine testing performed by service technicians, public and semipublic pool operators, and other professionals. Taylor’s 2000 Series uses printed color standards to achieve a reliable and accurate color match, making frequent test comparisons even easier. 2000 Series kits feature six different standards for chlorine (High Range: 0.5-5 ppm, Low Range: 0.25-2.5 ppm), bromine (HR: 1-10 ppm, LR: .5-5 ppm) and pH (7.0 to 8.0).
