Description

Gastec P-9-H Permeation Tube Nitrogen Dioxide

Gastec P-9-H (also cataloged as P9H) is a certified, high-emission Nitrogen Dioxide ( $\text{NO}_2$ ) permeation tube engineered as a primary trace-gas generation standard for producing known, higher-concentration span gases of nitrogen dioxide gas.

While standard-emission tubes (such as the P-9-1 model) are optimized for ultra-low trace concentrations, the H-suffix (High-emission) variant features elevated membrane permeability to deliver a higher nanogram-per-minute ( $\text{ng/min}$ ) release rate. This makes it ideal for calibrating mid-to-high range gas analyzers, verifying colorimetric detector tubes, and auditing industrial safety systems.
