Description

Gastec P-3-M Permeation tube ammonia

Gastec P-3-M (also cataloged as P3M) is a certified Ammonia ( $\text{NH}_3$ ) permeation tube engineered to serve as a primary trace-gas calibration standard for generating accurate, low-concentration ammonia gas streams.

When used inside a constant-temperature dynamic gas calibration generator (such as the Gastec PD-1B or standard laboratory gas calibration systems), it emits a certified, continuous mass flow of pure ammonia vapor through a fluoropolymer membrane into a controlled dilution air or nitrogen carrier stream.
