DESCRIPTION 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 H2 that is compensated for the interference effects of CO, CO2, and CH4. This ensures that H2 will always read correctly regardless of the background gas composition. A long-life eletrochemical sensor is used for PPM or % O2 analysis. Sensors are temperature-controlled or temperature-compensated for maximum stability. All...
