The Marine Line Ammonia Checker HC by Hanna Instruments is a handheld colorimeter designed to measure ammonia levels in saltwater aquariums. It uses the Beer-Lambert principle and an LED light source at 610 nm, along with a silicon photocell detector, for accurate readings within the range of 0.00 to 2.50 ppm NH3. The device employs an adaptation of the Salicylate method where ammonia reacts with reagents to produce a blue-green tint in the sample, allowing precise measurement without complex setups.
