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.
