The HI-715 Checker is an accurate and reliable digital tester for measuring ammonia within freshwater, making it an ideal option for use in freshwater aquariums. This simple, easy-to-use Checker requires a 10 ml sample of water from your tank and features a single-button operation for fast digital testing results to give you immediate insight into the ammonia levels in your aquarium.
The HI-715 digital tester covers a medium range for ammonia testing, from 0.00-9.99 ppm. A single included AAA battery is required for continual testing, with an auto power-off feature after 10 minutes of inactivity to further prolong battery life.
Ammonia is produced in fish tanks through natural processes, including excretion from the gills, urine and faeces of fish, alongside the decomposition of organic matter and food within the aquarium. Too much ammonia can cause burns to the skin and scales of fish and reduces their ability to filter oxygen effectively through their gills. High ammonia levels also lead to algae growth, which in turn affects pH levels in your tank.
Measuring ammonia with this accurate digital colorimeter tester allows you to immediately see the levels of this parameter in your tank. With prompt, accurate information, you can make swift changes to protect your tank and ensure your fish have the correct water chemistry levels within the aquarium for optimal health.
The HI-715 uses an adaptation of the ASTM Manual of water and Environmental Technology D1426-93, Nessler Method. In this method, the reagents that are provided with the Checker are added to the sample vial to create a measurable reaction. The reaction between ammonia and reagents causes a yellow tint in the sample, which is then read by the Checker to provide a clear, digital readout of ammonia levels in parts per million.
The HI-715 includes a reagents starter kit for 25 tests, so you can start testing the ammonia in your aquarium immediately out of the box.
