This is a Taylor Midget Chlorine DPD Tablet 0.2-3.0 ppm Test Kit. The K-1234 Kit tests for free and total chlorine using a midget comparator system and DPD tablets.
Chlorine itself is one of the most important chemicals to monitor if you have a chlorinated pool. Ideally, you should be testing every day, especially if your pool is not covered and is exposed to rain, wind, leaves, grass clippings, and sunlight. The chlorine level should stay between 1.0 and 3.0 parts per million (ppm) to maintain a healthy pool.
