Save time and money: Provides accurate measurements of pH and residual chlorine so you adjust pool chemicals only when needed instead of guessing or over-treating. Reduce health risks: Regular testing of pH and chlorine levels helps keep water in safe ranges, lowering the risk of ear and skin infections and waterborne gastrointestinal illness from microbial growth. Fast, reliable results: The tester delivers quick, precise readings for both pH and residual chlorine to help you keep your pool or spa safe for swimmers. Easy operation: The electric test system is simple to use for routine monitoring—no complex procedures required—making it practical for homeowners, pool technicians, and facility staff. Compatibility: Designed for use with swimming pools, hot tubs/spas and other water sources where pH and residual chlorine need routine monitoring. Core functions and performance: Measures pH and residual (free) chlorine, providing actionable values so you can dose chemicals accurately and avoid over- or under-treatment. Typical applications Home pool maintenance: Check pH and chlorine before family swim times or weekly maintenance to keep water balanced and safe. Spa and hot tub care: Monitor chlorine residual and pH regularly to protect sensitive skin and prolong equipment life. Facility or seasonal checks: Use for routine water quality checks in community pools, fitness clubs, or other water features to ensure consistent treatment.
