  • Analogue I/O, Event relays
The speed of sound in a binary gas mixture depends on temperature, heat capacity, and molar mass of the mixture. By precisely measuring the speed of sound and temperature, and knowing the thermodynamic properties and molar masses of the gases, the SRS BGA244 determines the exact composition of gas mixtures. The BGA244 provides a hundred fold improvement in stability, accuracy and resolution over thermal conductivity analysers. It operates without lasers, filaments, chemical sensors, optical sources, separation columns, reference gases, or reagents, and runs virtually maintenance-free. It also lets you choose from 500 gases, enabling you to measure thousands of mixtures. The BGA244 does not require zero or span calibration to achieve 0.1% accuracy. This eliminates the need for reference, zero and span gases, plus the valves, labour or software needed to perform them; leading to a lower cost of ownership. This, plus the improved accuracy and wide range of gases, dramatically improves the value proposition for the BGA244 when compared to other analysers. The BGA244 is ideal for a host of applications including binary gas blending, PSA (pressure swing adsorption), helium recovery, ozone purity, dopants and carrier gases, industrial gas processes and general research where precise and reliable measurements of gas mixtures are essential.
