Taylor Technologies
Taylor Slide Comparators are systems for colorimetrically determining solute levels in water. In each test, a liquid sample is treated with reagents causing a color to develop. The K-1741STR comes with the capability to test for Total and Free Chlorine, pH, Total Alkalinity, and Calcium Hardness. It contains a Slide comparator with 9 color standards, the Watergram Water Balance Calculator, and inside is an attache-style carrying case so you can take your lab poolside.
