Measure free chlorine levels in water and on surfaces to verify disinfection efficacy, support regulatory compliance, and maintain safe hygiene standards. Designed for routine and specialist testing, this test is used to monitor key water quality parameters and support effective treatment programmes. Applications include pools, spas, aquaculture, drinking water, wastewater and environmental sampling. Fast visual results allow users to make informed maintenance decisions without laboratory instrumentation. Complementary water chemistry tests are available for broader parameter monitoring.
