Description

Gastec P-181-H Permeation Tube Dimethylamine

Gastec P-181-H (also cataloged as P181H) is a certified, high-emission Dimethylamine ( $(\text{CH}_3)_2\text{NH}$ / DMA) permeation tube used as a primary trace-gas generation standard for producing known, continuous concentrations of dimethylamine vapor.

When housed inside a constant-temperature dynamic gas calibration generator (such as the Gastec PD-1B or standard laboratory calibration diluters), it releases a certified micro-rate mass flow of pure dimethylamine through a fluoropolymer membrane into a controlled dilution air or nitrogen stream.
