Colorimetric Gas Detector Tubes

Colorimetric gas detection tubes are gas detection equipment used for punctual needs or when there is no available classic device to monitor some gases or substances. Single-gas detection tubes measure levels of a single gas. Tubes are flame sealed glass tubes containing treated adsorbent granules that react with a specific compound or group of compounds, causing the adsorbent to change color. They are used with gas detection hand pumps to spot check air in a facility for hazardous gasses or chemical vapors.
