This test paper allows the quick and easy detection of strong oxidizers such as nitrite and free chlorine. Potassium iodide starch paper is also used to control diazotization reactions. Nitrite or free chlorine oxidize potassium iodide to form elemental iodine which reacts with starch to a blue-violet complex. Potassium iodide starch paper may be used by dipping it into the sample or by applying drops of the sample onto the paper. To detect gaseous oxidizers, the paper is moistened with distilled water and then exposed to the gas in question.

The Dräger-Tubes^® measuring system is the safe method for measuring pollutants in the soil, water and air. More than 500 substances can be measured in varying concentrations. The long-established principle of Dräger-Tubes^® is still the same. A defined volume of gas/air must be pumped through the sampling tube. This can be achieved by using the Accuro^® gas pump. On contact with the substance under test the reagent system contained in the tube reacts and displays a colour. The strength of the concentration of the substance is shown by the length of the colour band displayed and can be read directly from the scale. The Dräger-Tubes^® sampling system provides accuracy, efficiency, quick and easy handling. Over 250 tubes are available on request for all substances and measuring fields. Further sampling devices, diffusion tubes for long-term measurements as well as sampling systems with activated carbon tubes, ORSA collector and TDS thermodesorption tubes are also available.

Roll length 5 m, 10 mm width. With two colour zones. Plastic box with 1 roll of indicator paper and colour scale. Duotest indicator papers combine two different indicator zones on a single strip. The zones are separated by a hydrophobic barrier, which effectively prevents mixing of the reaction colors, simplifying and precisely assigning the pH value.
