What is a detector tube?

A detector tube is a specialized instrument used to measure the concentration of specific contaminants in the air. It operates on the principle of chemical reaction, where the air sample being tested passes through a tube that contains certain reactive substances. When the sample enters the tube, a chemical reaction occurs, leading to a color change. The degree of this color change corresponds to the concentration of the contaminant present, effectively providing a visual indication of the levels of hazardous substances in the environment.

This method is particularly valuable in confined space situations, where rapid and accurate detection of harmful gases is crucial for ensuring the safety of workers and rescuers. Detector tubes are often portable and easy to use, making them ideal for field applications where immediate results are needed.
