产品简介：
Two models are available. The M60 (%) measures oxygen from 0 to 5000 ppm to 0 to 25%. The M60 (ppm) measures oxygen from 0 to 200 ppm to 0 to 5000 ppm using electrochemical technology to deliver accuracy and stability.
应用：
Oxygen in natural gas gathering pipelines sometimes need to be monitored to ensure streams do not exceed maximum allowed concentrations of oxygen. Common ranges are from 0 to 2,000 ppm and 0 to 25%. Vapour recovery systems where inlet compression pressures are sub-atmospheric, are susceptible to air infiltration and oxygen concentration monitoring serves as an early warning. Storage tank blanket gas and other head space applications frequently require oxygen monitoring for safety reasons.
