OXS-3100 Series – Gas Composition Monitor
Gas composition analyzer designed for on-line process monitoring and control. It monitors gases from ppm to percent levels with sub-second update rate. Measurable gases include CO, CO₂, NO_x, SF₆, NF₃, HCl, H₂O, hydrocarbons, CFCs and many others. Download brochure.

OXS-4100 Series – Trace Gas Monitor
The analyzer is designed for high sensitivity measurement requiring low ppm to ppb detection limits. In a single compact 19-inch rack mount, it can monitor up to eight user-selected compounds, thus eliminating the need for multi-sensor integration. An embedded, solenoid controlled, two-inlet sampling system enables programmable automatic zeroing, calibration verification and/or multiplexing. Download brochure.

OXS-100 OptixSense™ In-Line Process Gas Analyzer for OEMs
The OXS-100 OptiXsense™ Optical Gas Analyzer is a high-performance low-cost solution for composition and trace gas monitoring. Employing the same innovative tunable filter spectroscopic engine as our other analyzers, the OptiXsense™ enables high accuracy multi-gas analysis in a compact package and is ideally suited for volume quantity applications currently requiring multiple NDIR sensors.
