QUANTOFIX Nitrate/Nitrite test strip enables the quick and reliable determination of nitrate and nitrite in water–based liquids. The simple handling makes the test strip particularly user–friendly: simply dip it into the sample, wait briefly and read off the result – in less than 70 seconds! The test strip can be evaluated with the included color scale as well as instrumental with the QUANTOFIX Relax strip reader. In addition to a convenient measuring procedure, this also offers automated and digital documentation of the results. QUANTOFIX Nitrate/Nitrite is versatile, e.g. in dairies for checking nitrate and nitrite levels in milk products, in vegetable production for analyzing fertilizer residues or in drinking water monitoring. QUANTOFIX Nitrate/Nitrite is the ideal solution for anyone who needs a quick, simple and precise nitrate/nitrite determination.
