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.\u003c\/p\u003e \u003cp\u003eThe HI-784 covers a comprehensive range of marine ammonia, from 0.00 to 2.50 ppm (mg\/L) in NH\u003csub\u003e3\u003c\/sub\u003e. An included AAA battery is required for digital testing, with an in-built automatic power-off feature to save battery life between tests.\u003c\/p\u003e \u003ch2\u003eWhy measure marine ammonia?\u003c\/h2\u003e \u003cp\u003eAmmonia 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.\u003c\/p\u003e \u003cp\u003eUsing 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.\u003c\/p\u003e \u003ch2\u003eHow does the HI-784 work?\u003c\/h2\u003e \u003cp\u003eThe 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.\u003c\/p\u003e \u003ch3\u003eCheckers vs test kits\u003c\/h3\u003e \u003cp\u003eChemical 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.\u003c\/p\u003e \u003ch2\u003eWhere can the HI-784 Marine Ammonia Checker be used?\u003c\/h2\u003e \u003cp\u003eThe HI-784 digital Checker is specifically designed for use in saltwater and reef aquariums.\u003c\/p\u003e \u003ch3\u003eFeatures:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eCompact, handheld design\u003c\/li\u003e \u003cli\u003eAccurate to ±0.05 ppm ±5% of reading\u003c\/li\u003e \u003cli\u003eDedicated to a single parameter\u003c\/li\u003e \u003cli\u003eSingle AAA battery required (included with Checker)\u003c\/li\u003e \u003cli\u003e10 minute auto-power-off functionality\u003c\/li\u003e \u003cli\u003eBuilt-in timer for reaction readings\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eOrder Information:\u003c\/h3\u003e \u003cp\u003eThe HI-784 Checker is supplied with 2 cuvettes and caps, a plastic refilling pipette, marine ammonia reagent test starter kit x 10 tests (\u003cspan\u003eHI-784-25\u003c\/span\u003e), 1 x 1.5V AAA battery, and an instruction manual.\u003c\/p\u003e \u003cp\u003eOrder more reagents with code \u003cspan\u003eHI-784-25\u003c\/span\u003e for the HI-784 Marine Ammonia Checker\u003c\/p\u003e \u003ch3\u003e\u003c\/h3\u003e \u003ch3\u003eSafety Data Sheets\u003c\/h3\u003e \u003cp\u003eWhen using any form of chemical, such as Hanna reagents, it is important you download the relevant safety data sheet and make yourself aware of any precautions you should take when handling the chemical.
