Quick and accurate readings of pH and chlorine (Cl2) levels for pools, spas, and other water sources. This electrical tester is designed for routine monitoring to keep water safe and clean. - Function and design: handheld, portable tester that measures pH and chlorine levels for regular checks in a variety of water sources. - Why it matters: when chlorine and pH are out of balance, health issues can occur such as diarrhea and ear or skin infections. A high pH reduces chlorine effectiveness, while organic matter from urine, sweat, sunscreen, or excreta consumes chlorine. - What you gain: helps keep a pool or spa within a safe chlorine and pH range without chemicals or guesswork. - Compatibility and use: suitable for residential pools, spas, hot tubs, and other water sources that require routine monitoring. - Use scenarios: daily home pool maintenance; spa upkeep to protect skin and comfort; monitoring water in small public pools or outdoor features. - Performance: provides quick, reliable readings to support timely adjustments and maintain water cleanliness and safety.
