Additional information

Airtec tubes are a simple and convenient system for monitoring gas cylinders, compressed breathing air and airline systems. As industrial applications often produce, or are performed in the presence of harmful contaminants, it is essential to test these air supply units before using them. When self-contained breathing apparatus (SCBA) or other devices are used for operators breathing protection, breathing air quality requires special attention. Contaminants that may enter a compressor or contaminants generated can be harmful to the user and the protective equipment.


The Airtec Tube gas detection is a convenient and economical system for testing the quality of compressed breathing air. Measurement process is swift and easy to perform and requires no training or calibration.


Contrary to colorimetric gas detector tubes, Airtec tubes do not require a sampling pump but a breathing air quality test kit which is intrinsically safe and can be used in any situation. Airtec tubes can detect the most common contaminants in compressed gas and supplied air systems. Indeed, they can monitor evaluate concentrations of carbon monoxide (CO), carbon dioxide (CO2), water vapor (H2O), nitrogen oxides (NO and NO2) and oil mist.


The measurement procedure is quite easy to perform and requires only a few minutes. First, snap off both ends of the tube and insert the tube into the tube holder with the arrow pointing down. Then, adjust the flowmeter to the specified flow rate and note where the color stain stops. As soon as the sampling time is finished, turn off the air supply and get immediately instant reading of the contaminant concentration directly on the tube. This way, Airtec gas detector tubes require no specific training or technical skills so that anyone can use them quicly and safely.


Airtec detector tubes are supplied in packs of 10 and are designed to meet monitoring requirements set in Standard G-7.1.Tubes by the Compressed Gas Association (American trade association for industrial and medical gas supply industries).
