Stanford Research Systems BGA244[/caption]
The BGA244 Binary Gas Analyser from Stanford Research Systems (SRS) is a new product harnessing the fundamental physical principles of acoustic resonance to measure the speed of sound in a gas mixture and provide gas ratio measurements with errors as low as 100ppm. This technique has advantages over conventional thermal conductivity binary gas analysers with SRS’ implementation providing a dramatic improvement in performance and value:
