This is a Midget Comparator Bromine DPD 2 Test Kit. The K-1773 Kit tests for total bromine using the midget comparator and DPD reagents.
If you use bromine instead of chlorine to sanitize your pool or spa, testing for bromine is essential. In general, your bromine level should be 3-5 parts per million (ppm). Right after you shock your pool or spa, the number may be higher.
