Description This test strip detects ammonia in increments of 0, 10, 25, 50, and 100ppm. This Ammonia test strip is designed to work for the detection of ammonia (NH3/NH4 ) in water IT WILL NOT detect combined ammonia compounds like chloramines. This strip is designed to measure higher concentrations of Ammonia such as in bioreactors and some industrial applications, it is NOT for testing aquarium water which requires a lower test range. We recommend this test for measuring ammonia in aquariums. How to test for ammonia: Remove one test strip from the container and replace the lid. Dip the test strip into the solution being tested for 1 second. Remove test strip, and shake off excess water. Compare strip to the color chart after 5 seconds. Do not wait more than 10 seconds to compare to the color chart. The test strip works by using two pads in the test pad “sandwich” – the first pad creates an alkaline environment which converts all of the ammonia/ammonium present to ammonia. The second pad employs a hydrophobic material and indicators to detect the ammonia present. IMPORTANT NOTE: The color chart reads as ‘ppm ammonia-nitrogen’, not as ppm ammonia. As a result, a reading of 100 ppm on the color chart of ammonia-nitrate is equivalent to 122 ppm as ammonia. If you have any questions as to how to use this strip or how to interpret your reading please contact us and we will be happy to help!
