This is a Taylor Commercial Midget Comparator Chlorine/pH (DPD Low-Range) Test Kit. The K-9036 Kit tests for Free and Total Chlorine and pH using the midget comparator and DPD and Phenol Red chemistry.
Kits in the Commercial Series test for two closely related parameters using liquid-color standards. 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 ounce in Midget kits.
The chlorine level should stay between 1.0 and 3.0 parts per million (ppm) to maintain a healthy pool. A pool’s pH levels should be maintained between 7.2 and 7.6.
