A basic, quick, and accurate tool for measuring pH and chlorine levels in water. Chlorine is the most commonly used water disinfectant for killing algae and microorganisms, and this tester supports monitoring those levels. An electrical tester for pH and chlorine (Cl2) levels, designed for routine monitoring in swimming pools, spas, and various water sources. Keeps a pool or spa in a safe chlorine and pH range, without guesswork or unnecessary chemical adjustments. When chlorine and pH are out of balance, disinfection becomes less effective and health risks can increase. If the pH is too , chlorine effectiveness is reduced. The presence of nitrogen compounds (urine, sweat, sunscreen, excreta) and other organic matter also consumes chlorine. Key attributes and performance: Function: measures pH and chlorine (Cl2) levels for routine water testing Compatibility: suitable for swimming pools, spas, and various water sources Design: compact handheld tester for easy use Reliability: enables quick readings to support safe, wellbalanced water Use scenarios: Home pool maintenance: perform regular checks to keep water safe and comfortable for family use Spa or hot tub balancing: monitor pH and sanitizer levels to protect skin and eyes Community pools or rental properties: routine testing to ensure water quality for guests and residents
