Item # 975A, Continuous Analyzer for Syn-Gas Atmospheres - O2, CO, CO2, CH4 and H2


The Nova 970 Series Syn-Gas Analyzer System has been designed with the flexibility and robustness required in the experimental and developmental environments that characterize syn gas applications.

The Nova 970 Series 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 compensates for the interference effects of CO, CO2, and CH4. This ensures that H2 will always read correctly regardless of the background gas composition.  A non-depleting paramagnetic sensor is used for O2 analysis.  All sensors/detectors are temperature-controlled or temperature-compensated for maximum analytical stability.  Auto calibration functionality allows easy calibration without user intervention.  The included Serial Output Package allows connection of analyzer to personal computers via a choice of USB/RS-232/RS-485. Data recording software is also included.
