System Description
The Series 9510 Carbon Dioxide Monitor is designed to provide continuous, unattended measurement of carbon dioxide in breathing air environments. The Series 9510 Carbon Dioxide Monitor features an open sensor diffuser that allows free movement of ambient air to the sensor without the use of a sample pump. For monitors that require a sample pump to transport the sample, often the reliability of the measurement is contingent on the pump working properly which may not always be the case.

The focal point of the Series 9510 is its state-of-the-art sensor technology. Alpha Omega Instruments carbon dioxide sensor features a next generation NDIR (non-dispersive infrared) measuring system. The carbon dioxide sensor incorporates closed-loop control for enhanced long-term calibration stability. The control signal is generated by means of an optical referencing element that monitors source intensity.

This methodology, coupled with a novel source homogenizing gas sampling chamber, yields a system with greatly improved tolerance to changes in the infrared source outputs.
