• Ideal for short term measurement and low level detection
• Uses simple colour change technology
• Determining and measuring concentration peaks
• Detecting leaks in pipelines gas installations, etc
• Air analysis in sewers, shafts and confined spaces

Gastec Detector Tubes are used in environments where sampling, screening and TWA measurement is required. They are of the highest quality for accurately analysing a wide variety of gases, vapours and ground substances. The glass tubes are filled with chemical reagent that absorbs and reacts with the target gas or vapour being measured. A colorimetric stain (a colour change) is created. For most tubes, the concentration is read directly from the pinpoint accurate measurement scale on each tube. This form of monitoring is ideal for spot sampling as it can be more accurate then electronic gas detectors.
