Commercial Slides DPD Chlorine-High and pH Test Kit.
Kits in the Commercial Series test for two closely related parameters using liquid-color standards. The Slide and Midget comparators in this series give the most accurate colorimetric readings available short of high-end electronic instrumentation. Cases are custom-molded plastic. Reagents are .75 oz. in Midget kits and 2 oz. in Slide kits. If you are an operator or regulator of a commercial facility and you dont see the ranges or combinations to meet your local ordinances, call our Customer Service Department.
