Overview
Nitric acid vapor HNO3 detection tube type detector toxic tube $r $n nitric acid gas detection tube $r $n $r $n The nitric acid detection tube is a sealed slender glass tube that presents a specific color due to being filled with specific reagents and coloring agents. When a gas sample containing nitric acid enters the detection tube, a chemical change occurs, causing a change in color. The scale corresponding to the boundary of observing color changes is the concentration of nitric acid in the tested sample.
