Model 5000

Portable System to measure gas purity (99.99%) for over 500 different gases plus single digit ppms for Oxygen and Water Vapor

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. This allows the Model 5000 to achieve gas purity measurements up to 99.99% with an accuracy of approximately 0.1%.

The Model 5000 includes data on nearly 500 gases such as CO2, H2, SF6, N2, Ar, He and O2, accessible via a 7” touch screen panel or remotely through a digital interface. Users can also add gases to the data table. Additionally, ASTG has integrated electrochemical sensors capable of measuring H2O and O2 down to single digit parts per million (ppm).

Equipped with a long-lasting battery, data logging/control software, analog and Modbus communications connections, and sample inlet/outlet ports, the system is housed in a rugged pelican carrying case with a handle. This design ensures durability and portability, making it suitable for a variety of research applications, verification, and testing across different environments.

Overall, the Model 5000 delivers cost-effective analysis with consistent high performance and minimal maintenance requirements. Its highly stable measurement technologies reduce the need for frequent user calibration, facilitating long-term deployment. Combining the precision of laboratory-grade analyzers with portability and flexibility, the Model 5000 meets the demands of diverse research and testing scenarios.
