The Nova 7900 Series Heat Treat Analyzer System utilizes high stability infrared detectors for the simultaneous measurement of CO, CO2, and CH4. In addition, the analyzer can also be supplied with a non-consumable, long life thermal conductivity cell for hydrogen that is compensated for the interference effects of CO, CO2, and CH4. This ensures that Hydrogen will always read correctly regardless of the background gas composition. A long life electrochemical sensor is used for PPM or % O2 analysis. In most cases, sensors are installed in a temperature controlled box to improve reading accuracy. All detected gases have a separate digital readout and linear recorder output. Various versions available for either exothermic or endothermic mixtures, or for other industrial process gases.
