Quantofix Nitrite test strips for the semi-quantitative determination of nitrite NO2 - in solutions.

Quantofix Nitrite 3000 test strips for the semi-quantitative determination of high concentrations of nitrite (NO 2- ) in solutions. Between pH 2 and 12 the reaction is independent of the pH value of the test solution. Adjust strongly acidic solutions with dilute sodium hydroxide solution and strongly alkaline solutions with dilute sulphuric acid to a pH of about 4 to 6.

Color change white to red-violet for 1-80 ppm strips. Color change yellow to red for 100-3000 ppm strips. Store nitrite test strips in a cool and dry place, protected from sunlight and moisture.
