Chlorine pH CL2The basic tool to quickly and precisely measure pH and chlorine is the most common water disinfectant used to kill bacteria, algae and microorganisms.The ideal tool for keeping pools or spas in a safe pH and chlorine beach, without any chemical or conjecture.An electric tester for pH and chlorine levels (CL2) for routine monitoring of pH and chlorine levels in swimming pools, spas and various water sources.When chlorine and pH escape, this can cause diarrhea and ears and skin infections. A good chlorine and a good pH guard the bad bacteria in the bay: if the pH is too high, the electricity killed by the chlorine will be exhausted. When large quantities of nitrogen (feces, urine, sunscreen or sweat) or other organic substances penetrate in the pool, chlorine is also consumed. That's why it's always better to test chlorine and pH - it can change every day depending on the use of the pool. Maintain your pH in the appropriate range is important to maintain surface treatment of equipment and pools. Your chlorine will dissolve more quickly to a low pH. The high pH value will invalidate the gaseous chlorine.This electrical measuring instrument can save you time and money.Note: Except for pool or spa water, the detector will not plunge recommendations in the water.DatasheetThe recommended chlorine content for pools and spas is 1.2 to 1.7 ppmThe recommended pH for swimming pools and spas is 7.2 to 7.8sizeMain unit: 180 mm x 20 mmHandle probe: 150 mm longProbe (limited to): 48 mm longCable (only): 300 mm longPower supply: 1 AA alkaline battery (1.5 V)Naked metal weight: 193G B (without battery)Gross weight: 260gIncluding the size of the package 200 * 150 * 70 mmDelivery quantity:1 pH probe tester and cl21 Manual1 Paper sheet
