QUANTOFIX Ammonium test strips provide a fast and reliable way to measure ammonium in water-based liquids. Designed for simple semi-quantitative testing, the strip is dipped into the sample, allowed to react briefly, and then compared with the included colour scale for easy result interpretation.
These test strips are suitable for monitoring ammonium levels in surface water, drinking water, industrial wastewater, aquariums, fish farming, and aquaculture. The test uses the Nessler method and shows a clear colour change from bright yellow to orange, helping users identify ammonium levels quickly and confidently.
For enhanced accuracy and digital record keeping, the strips can also be evaluated using the QUANTOFIX Relax reflectometer. Each pack includes 100 test strips in a tube with additional reagents supplied in the box.
