Series 9500氧气和二氧化碳检测器

The Series 9500 Oxygen and Carbon Dioxide Monitor is designed to provide continuous, unattended monitoring of both oxygen and carbon dioxide.

System Description
The focal point of the Series 9500 is its state-of-the-art sensor technology. The oxygen sensor features a patented extended life electrochemical sensor with EES (enhanced electrolyte system). EES retards passivation of the sensor anode by allowing the products of oxidation to dissolve in the electrolyte. As a result, sensor life is extended.

Alpha Omega Instruments has complemented its oxygen sensing capabilities with its 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.
