This precision analyzer has a range from 0 to 100%, other ranges are available on request. It is typically used to determine the O
2 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.
