There are vials for 25 tests to be used with Hanna’s HI801 and HI802 spectrophotometers. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with lot number and expiration date for traceability. The method used is an Adaptation of the Nessler Method, which ensures very quick results in a wide range, especially for wastewater. The procedure is very fast (3 and a half minutes), it involves the addition of a very representative sample volume (5 mL for the Low Range) and the use of 13 mm (internal diameter) cuvettes, with a longer optical path than many other vials on the market. This ensures accurate absorbance measurements and greater repeatability of results. The reagents can be stored at room temperature. Signicance and Use Ammonia analysis is crucial for evaluate water quality and environmental impact. In natural waters, elevated ammonia levels can indicate organic pollution and pose risks to aquatic life. In wastewater, ammonia measurement helps evaluate treatment e´ciency and ensures regulatory compliance. Regular monitoring is essential for maintaining ecological balance, optimizing treatment processes, and protecting public health. Application Ammonium ions and dissolved ammonia in groundwater and surface water, drinking water, wastewater, swimming water. 7 Reasons to Choose Hanna 1. Wide scale from 0 to 100 ppm which allows you to measure any input value without making a wrong scale 2. Very quick analysis: 3 and a half minutes! 3. Very representative sample (5 mL for low range, 1 mL for high range) 4. Ideal for wastewater analysis 5. The reagents can be stored at room temperature (up to 20/25°C) 6. Space-saving packaging with procedure guide on inside lid 7. Safe and Economical: Hanna reagents are safe for the operator and the environment.In fact, vials and caps have been designed to avoid accidental spills.Thanks to the reagents in premeasured vials, the amount of chemicals used is reduced to a minimum.
