Description
Gastec P-9-1 Permeation Tube Nitrogen Dioxide
Gastec P-9-1 (also cataloged as P91) is a certified, standard-emission Nitrogen Dioxide (NO2) permeation tube engineered as a primary trace-gas generation standard for producing known, continuous, low-ppm concentrations of nitrogen dioxide gas.
When placed inside a constant-temperature dynamic gas calibration generator (such as the Gastec PD-1B or single-channel PD-1C permeaters), it releases a certified micro-rate mass flow of pure NO2 through a polymer membrane into a controlled carrier air or nitrogen stream.
