This precision analyzer has a range from 0 to 10%. It is typically used to determine the CO2concentration in respired gases or gas mixtures from collection bags, or
other sources. May be adjusted to 0 to 15% on request.
The instantaneous CO2 concentration or the highest value during a breathing cycle (EtCO2) is displayed on a digital meter and 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 may be installed on request at no charge.
Precision gas mixtures are available for calibrating the analyzer.
