Hydrochloric Acid Detection Tubes
Manufacturer: Draeger
Draeger's Hydrochloric Acid Detection Tubes are simple to use, inexpensive and portable, with calibration not required. The wider diameter of the Draeger-Tubes makes it easier to read. Well-spaced graduation marks enable distinct and decisive measurement results. Color changes to the reagents are well defined over the entire length of the stain. Many Tubes offer a dual calibrated scale so that you can interpret the results without using multiplication factors. No interference on the reading of 10 ppm H2S and 2 ppm SO2. Other acid gases are also indicated, however, with differing sensitivity. Chlorine changes the indicating layer to grey. If chlorine occurs simultaneously, HCl readings will be higher. Color change is revealed with HCl + bromophenol blue ‚Üí yellow reaction product.
