Description
Gastec P-9-1 Permeation Tube Nitrogen Dioxide is a specialized device used for generating high-precision calibration gas. By utilizing the principle of permeation, this tube allows for the controlled release of $NO_2$ gas through a semi-permeable membrane at a constant rate when maintained at a steady temperature. This method is far superior to static gas mixtures, as it ensures a fresh and consistent concentration for critical calibration tasks.
Whether you are performing routine bump tests or complex laboratory analyses, this permeation tube serves as a reliable reference standard. Because each permeation tube has individual differences in permeation rates, the actual range that can be controlled may differ slightly from the standard concentration range. This characteristic allows for fine-tuning your calibration setup to achieve specific target concentrations with extreme accuracy.
