Product manualColor: chlorine ph Cl2 testerThe basic tool for quickly and accurately measuring pH and chlorine is the most common water disinfectant used to kill bacteria, algae and microorganisms.The ideal tool for keeping swimming pools or spas within a safe pH and chlorine range without any chemicals or guesswork.An electrical tester for pH and chlorine (Cl2) levels for routine monitoring of pH and chlorine levels in swimming pools, spas and various water sources.When chlorine and pH escape, it can cause diarrhea and infections of the ears and skin. Good chlorine and good pH keep bad bacteria at bay: if the pH is too high, the electricity killed by the chlorine will be depleted. When large amounts of nitrogen (faeces, urine, sunscreen or sweat) or other organic substances enter the swimming pool, chlorine is also consumed. This is why it is always best to test for chlorine and pH - it can change every day depending on the use of the pool. Maintaining your pH in the proper range is important in maintaining the surface treatment of equipment and swimming pools. Your chlorine will dissolve faster at low pH. The high pH value will invalidate the chlorine gas.This electrical measuring instrument can save you time and money.Note: Except for pool or spa water, the detector will not immerse the recommendations in water.Specification tableRecommended chlorine content for swimming pools and spas is 1.2 to 1.7 ppmThe recommended pH for swimming pools and spas is 7.2 to 7.8CutMain unit: 190mm x 20mmHandle probe: 150mm longProbe (limited to): 48mm longCable (only): 300mm longPower supply: 1 AA alkaline battery (1.5 V)Weight: 160g b (without battery)Include the set1 pH and Cl2 probe tester1 manual1 sheet of sandpaperStandard factory packing
