Rapid Gas Detection Tube

A rapid gas detection tube is a glass tube filled with chemical colorimetric reagents. During use, a hand pump is employed to draw a specific volume of gas. The target gas reacts with the reagents, resulting in a color change, and the concentration is quantified based on the length of the color change. It is used for on-site rapid detection of toxic and harmful gases, commonly applied in factory safety monitoring and environmental inspections.
Selection
When selecting, it is essential to clearly identify the type of gas to be measured, match the detection tube's range with the on-site concentration, pay attention to the influence of interfering gases, check the validity period and storage conditions, and consider compatibility with the hand pump as well as the temperature and humidity requirements of the operating environment.
