Gastec Airtec Tubes
The Airtec Tube is a convenient, economical system for testing the quality of compressed breathing air. Measurement is quick and simple and does not require user training or calibration. Just snap off both pre-scored ends of the tube, insert the tube into the tube holder with the directional arrow pointing down, and adjust the flowmeter to the specified flow rate. After the required time, note where the colour stain stops and immediately take the measurement from the direct-reading tube.
Tubes are supplied in packs of 10.
A kit for measuring compressed breathing air for impurities is available, using the carbon monoxide, carbon dioxide, water vapour and oil mist Airtec tubes.
