ONE good chlorine and pH level keeps bad bacteria on bay: When pH goes up too high, chlorine's germ-killing power deflates. Chlorine can also get eaten up if a lot of nitrogen (from debris, puddles, sunscreen, or sweat) or other organic gets into the pool. That's why it's best to test chlorine and pH levels all the time-they can change day to day based on pool use. Keeping your pH levels within the proper range is important for keeping your equipment and pool finish intact. Your chlorine will dissolve faster with low pH levels. High pH levels make chlorine inactive.Save time and money with this electro tester.NOTE: Probes are advisable DO NOT immerse in any liquid other than pool or spa water.SpecificationsRecommended chlorine level for pools and spa is 1.2 to 1.7ppmRecommended pH level for pools and spa is 7.2 to 7.8DimensionMain unit: 190x120mmProbe with handle: 150mm longProbe (alone): 48mm longCable (only): 130mm longPower supply: 1 x AA Alkaline Battery (1.5V)Weight: 160g (excluding battery)Set Included1 x pH and Cl2 Tester with Probe1 x Manual1 x Sand PaperStandard Factory Packaging Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
