This precision analyzer has a range from 0 to 100%. It is typically used to determine the O₂concentration in respired gases or gas mixtures from collection bags, or other sources.

The O₂ concentration is displayed on a digital meter. With the end-tidal (EtO₂) option the lowest value during a breathing cycle may be displayed. Corresponding analog voltages are available on rear panel BNC connectors.

A gas pump is built in to draw the gas through the analyzer.
A flow meter indicates the gas sample flow. Gas flow is internally adjustable. Adjustment may affect response time. A gas return port on the rear panel is standard.

Precision gas mixtures are available for calibrating the analyzer.
