HI-784
The HI-784 Marine Ammonia Checker is an easy-to-use, handheld digital ammonia tester for measuring the water in saltwater and marine aquariums. This innovative Checker allows you to accurately measure ammonia in marine aquariums, with a range from 0.00 to 2.50 ppm.
This Hanna Checker is a more accurate alternative to test kits and strips, with results displayed clearly on the screen and single-button operation. The Checkers range includes various ammonia test options for aquariums.
HI-784 Marine Ammonia Checker
The HI-784 Checker is a reliable, accurate electronic tester for measuring marine ammonia within saltwater, making it an ideal option for use in marine and reef aquariums. This practical Checker features a single-button testing process, enabling fast and convenient testing of water with clear, digital results on a large LCD screen.
The HI-784 covers a comprehensive range of marine ammonia, from 0.00 to 2.50 ppm (mg/L) in NH3. An included AAA battery is required for digital testing, with an in-built automatic power-off feature to save battery life between tests.
Why measure marine ammonia?
Ammonia is a natural process in all aquariums, through excretion from the gills, urine and faeces of fish, in addition to organic matter decomposition from plants and food in the fish tank. High levels of ammonia cause stress in fish, weaken their immune systems and may lead to ammonia poisoning, which can be fatal if uncorrected. In complex and often expensive marine fish tanks measuring ammonia is also important for understanding the success of tank cycling and biological filtration.
Using an electronic tester to measure marine ammonia provides accurate, direct results from testing with no need to compare the reaction to a colour chart. With prompt, precise information it’s possible to make faster changes to aquarium water chemistry for the health or your fish and the quality of your tank water.
How does the HI-784 work?
The HI-784 Marine Ammonia Checker is a handheld colorimeter that uses the Beer-Lambert principle to determine the concentration of ammonia colorimetrically. The HI-784 is designed specifically to measure ammonia levels in a saltwater aquarium. The 0.00 to 2.50 ppm range is ideal for coral/fish or fish only aquarium maintenance. Can also be used in marine biology.
Checkers vs test kits
Chemical test kits are a popular choice for marine ammonia. However, the manual perception required for these test kits require a certain degree of guesswork to determine the results of testing. Hanna Checkers are an ideal solution for accurate, reliable testing results, with the measurement displayed clearly on a digital LCD screen, ensuring you have the knowledge you need to appropriately manage your aquarium water quality.
