Used for detecting and measuring trace amounts of ammonia in water, air, and industrial processes. Commonly applied in environmental monitoring to assess water quality in aquariums, wastewater treatment plants, and rivers. Also used in laboratory analysis for qualitative and semi-quantitative tests in chemical and biological research. Helps ensure safety in agricultural and livestock facilities by monitoring ammonia buildup in ventilation systems. Suitable for field testing due to ease of use and rapid color-based results.
