The Models O2C, O2D and O2DAL are general purpose oxygen analyzers for research, air separation monitoring, and industrial monitoring applications. Designed to measure oxygen in a range of 5-100% accurately and in the presence of other gasses such as including Ar, He, H2, CO2 and non-condensing H2O vapors. The Model O2C features an internal pressure regulator to connection to 1-75 psig source and the Model O2D features a sampling pump for flow control. The Model O2DAL features a high flow micro pump for low pressure operation from 1200 to 55mbar (0-60,000 feet altitude).
