Choosing the Right Oxygen Purity Meter for PSA Systems in Torch Work: Why We Built a Self-Calibrating Ultrasonic Option
If you use a PSA oxygen system for glass, metal, or flame work, you’ve probably wondered how to verify the purity coming off your concentrators and into storage. We’re introducing a lower-cost, self-calibrating oxygen purity meter that uses an ultrasonic module (speed-of-sound) rather than the typical electrochemical, paramagnetic, or zirconia techniques. This post explains the…
