A good chlorine u0026 pH level keeps bad bacteria at bay: If pH goes up too high, chlorine's germ-killing power drains. Chlorine can also get eaten up if a lot of nitrogen (from debris, puddles, sunscreen, or sweat) or other organics 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 usage. Keeping your pH levels within the correct range is important for keeping your equipment and pool finishes intact. Your chlorine will dissolve faster with a low pH level. High pH levels make chlorine inactive.Save time and money with this electro tester.NOTE: Probes are advised NOT to 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 (only): 48mm longCable (only): 130mm longPower Supply: 1 x AA Alkaline Battery (1.5V)Weight: 160g (excluding battery)Kit Included1 x pH and Cl2 Tester with Probe1 x Manual1 x Sand PaperStandard Factory PackingPackaging DetailsUnit Type: Piece Package Weight: 0.221kg (0.49lb.)
