Series 9600 Oxygen and Carbon Dioxide Monitor

System Description

The Series 9600 Oxygen and Carbon Dioxide Analyzer is designed to provide continuous, unattended monitoring of both oxygen and carbon dioxide. The focal point of the Series 9600 is its state-of-the-art sensor technologies. The oxygen sensor is an extended life electrochemical sensor with EES (enhanced electrolyte system). This sensor provides exceptional accuracy and stability. EES retards passivation of the sensor anode by allowing the products of oxidation to dissolve in the electrolyte. In effect, the sensor is renewed continuously resulting in a significant increase in sensor life. In addition, the enhanced mechanical design of the sensor helps to ensure long life and virtually eliminates leakage of electrolyte, a nagging (and expensive) problem associated with other types of sensors.

Alpha Omega Instruments has complemented its oxygen measuring capabilities with a next generation NDIR (non-dispersive infrared) sensor. 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.
