Description
Gastec P-163-H Permeation Tube Ethylene Oxide utilizes advanced permeation technology to create a controlled release of calibration gas. Unlike traditional gas cylinders that can suffer from concentration decay or adsorption issues, this permeation tube provides a consistent mass flow rate by allowing the substance inside to permeate through its walls at a predictable rate.
When integrated into a compatible gas generation system, the P-163-H ensures a stable output by maintaining a constant temperature and flow rate. This makes it a superior choice for long-term calibration stability and secondary standard testing. It is important to note that because permeation tubes have individual differences in permeation rates, the actual range controlled may differ slightly from the standard concentration range of 0.5 – 23 ppm.
