An oxygen analyzer works by using an ultrasonic sensor to detect O2 concentrations. These sensors are based on the principle of sound wave speed, or ultrasonics. As sound travels through a gas, it propagates at different speeds and its intensity attenuates to different degrees depending on the composition of the gas. PPM O2 analyzers. On-line
