ASTG

AirBreather Systems™ was developed by ASTG at the request of one of the world’s largest gas manufacturers looking to update their gas purity verification system. 5 years of development, that included 2 years of field trials and 1 year of in-service validation, AirBreather Systems™ was born. A robust, economical, maintenance friendly system, incorporating state-of-the-art technology and proprietary software to provide fast, accurate, readily accessible gas purity verification.

ASTG Model 5000 – Portable Gas Purity Monitoring System provides continuous gas purity measurements based on the physical properties of gases present. Gas purity is determined by measuring the speed of sound in a resonant acoustic cell, alongside temperature in the gas mixture and knowledge of thermodynamic properties and molar mass.
