*taxes and shipping not included
Delivery time approx. 5 working days
The QUANTOFIX Ammonium test strip enables fast and reliable determination of ammonium in water–based liquids. Its simple handling makes the test strip especially user–friendly: just dip the pre–treated strip into the sample, wait briefly, and read the result! In addition to evaluation with the included color scale, instrumental analysis with the QUANTOFIX Relax is also possible. This offers not only a convenient measurement process but also automated and digital documentation of results. QUANTOFIX Ammonium is ideal for the rapid monitoring of ammonium, for example in surface water, drinking water, industrial wastewater, or home aquariums. The test also provides reliable support for monitoring critical limits in fish farming and aquaculture
