This precision analyzer has a range from 0 to 100%, other ranges are available on request. It is typically used to determine the O₂ concentration in respired gases or gas mixtures from collection bags, or other sources.

The oxygen concentration is displayed on a digital meter and a corresponding analog voltage is available on a rear panel BNC connector. A gas pump is built in to draw the gas through the analyzer. Gas flow is internally adjustable. Adjustment may affect response time. We can install a gas return port on request. Precision gas mixtures are available for calibrating the analyzer.

O₂ sensor lasts about 2 years, easily replaced by user.
