Hanna Instruments - HI784 Marine Ammonia Checker

The Ammonia Checker® HC (HI784) is a compact, digital tester designed to provide a simple, accurate, and budget-friendly way to measure ammonia (NH3/NH4+) in saltwater and marine aquariums. Ammonia is a natural byproduct of the nitrogen cycle, produced as aquarium inhabitants excrete waste. While beneficial bacteria normally process ammonia, imbalances can lead to toxic conditions that threaten tank inhabitants. The HI784 offers a highly precise alternative to traditional chemical test kits, delivering quick and reliable results with minimal effort. Ideal for saltwater aquariums, marine setups, and aquaculture applications.
