- Electro-tester for pH and chlorine (Cl2) in water, ideal for routine monitoring of pools, spas, and other water sources. - Save time and money by testing on site and dosing chemicals only as needed; reduces chemical waste and eliminates guesswork. - Keeping pH in the proper range protects equipment and pool finish; low pH increases chlorine dissolution, high pH reduces chlorine effectiveness. - Designed for routine monitoring of pH and chlorine levels to keep pools and spas within safe ranges. - Key attributes: function measures pH and Cl2; compatibility with pools, spas, and different water sources; performance provides reliable readings for ongoing maintenance. - Use scenarios: 1) Home pool maintenance: weekly tests to balance chlorine and pH. 2) Spa upkeep: monitor spa water to preserve comfort and protect equipment. 3) Small facilities: hotel pools, gyms, or community centers test water sources to ensure safe chemistry.
