The Model O2D is a general purpose oxygen analyzer for research, air separation monitoring, and industrial monitoringapplications. The Model O2C is designed to measure oxygen in a range of 5-100% levels and operates in XC mode for reliable measurements the presence of other gases including Ar, He, H2, CO2 and non-condensing H2O vapors. The Model O2C features an easy to use and feature bright LED displays, touch panel controls, easy calibratiom, and has a sampling pump and internal flow meter for monitoring flow in the system. A terminal strip on the rear panel is included for analog relay alarm outputs , 4-20 mA outputs, and an analog 0-1.0 VDC output is on a BNC connector. A DB-9 connector RS-232 digital output provides digital serial communications and is compatible with Oxisoft software. The unit has CPC O-ring quick connect inlet fittings for industrial applications.
