Perfect for both laboratory and field applications, Hach’s ammonia test strips provide a hassle-free solution for ammonia (nitrogen) detection. Ammonia is a byproduct of the microbiological breakdown of plant and animal proteins. In raw surface waters, the presence of ammonia typically signifies contamination from domestic or agricultural sources. Elevated levels of ammonia can pose a serious threat to aquatic life, particularly fish, making its monitoring essential for environmental health.
