Nunawading, Australia - Industrial Scientific Corp. says it recommends the use of urethane tubing when sampling exotic gases to prevent absorption of the gas by the sample tubing.
And clear urethane tubing has superior resistance to exotic gases, such as sulphur dioxide, chlorine and hydrogen chloride, than black tubing, the company said.
Urethane tubing provides effective resistance against the absorption of exotic gases while still remaining flexible and easy to work with. The type of sample tubing is important in gas detection systems, especially when sampling from a confined space, according to Industrial Scientific's Australian representative Air-Met Scientific Pty Ltd in a 30 May news release.
Industrial Scientific said it has identified, through its ongoing research related to portable gas detection monitors, that P/N 17065970 clear urethane tubing has superior resistance to absorption of exotic gases when compared to P/N 17102005 black urethane tubing.
This clear urethane tubing has a 1/8 inch (3.17 mm) inner diameter and 3/16 inch outer diameter, and is ideally suited for use with the pumped versions of Industrial Scientific's MX6 iBrid and Ventis MX4 gas monitors. The company will now include this clear urethane tubing with these pieces of equipment, and recommends that this tubing be used, effective immediately.
Industrial Scientific of Oakdale, Pennsylvania, also makes equipment for TDI (toluene diisocyanate) detection, such as the VX500.
