Product descriptionPH CL2 Chlorine TesterEssential tool for quick and accurate readings of ph & chlorine as chlorine is the most commonly used disinfectant for water by killing bacteria, algae and microorganisms. An ideal tool for keeping your pool or spa within the safe Chlorine and PH ranges, no more chemicals or no more guess work. An electro-tester for testing pH and chlorine (Cl2) levels in water for routine monitoring of pH and chlorine levels of swimming pools, spas and different water sources. When chlorine and pH levels go out of whack, it can lead to diarrhea and ear and skin infections. A good chlorine & pH level keeps bad bacteria at bay: If pH goes up too high, chlorine's germ-killing power deflates. Chlorine can also get eaten up if a lot of nitrogen (from debris, pee, sunscreen, or sweat) or other organic matter gets in the pool. That's why its best to test chlorine and pH levels all the time they can change day to day based on pool usage. Keeping your pH levels within the proper range is important for keeping your equipment and pool finish intact. Your chlorine will dissolve quicker with a low pH level. High pH levels make chlorine inactive. Save time and money with this electro-tester. NOTE: Probes are advice NOT to immerse in any liquid other than pool or spa water.
