Gas detector tube DSU-2M

Uniphos dissolved substance measurement tubes are an apt tool to measure the concentration of dissolved substances in wastewater by immersing the tube vertically in the sample solution. It is suitable for wastewater analysis in paper mills, petroleum refineries, chemical industries, etc. To measure, break both ends of the tube and place it in a beaker containing the sample water. Due to capillary action the sample water starts rising through the sensing reagent column. If the sample water contains the target ion, the colour of the reagent in the tube changes. The length of discoloration is proportional to the concentration of the dissolved substance present in the sample water.
