7900P SERIES PORTABLE INDUSTRIAL ANALYZERS APPLICATIONS For monitoring heat treating atmosphere or process gases in any combination of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), hydrogen (H2), oxygen (O2), and dew point. • Best value multi-gas portable analyzer • Fast warm up and response time • Long-life thermal conductivity cell for H2 • Long-life electrochemical O2 sensor • Sensitive infrared detectors for CO, CO2, and CH4 • H2 reading compensated for CO, CO2 and CH4 • LCD with backlight digital readouts • Modular layout that is easy to maintain • Rechargable battery operation • Built-in sample pump, flow meter and filters • Rugged bench top (BT) style cabinet • Recorder outputs of 0-1V or 4-20 mA • Condensate removal for wet sample gas applications • Suitcase (K) style cabinet available • AC only power operation • Sensors temperature-controlled for maximum stability (AC powered versions only) • Bright red LED displays in place of standard LCD CALIBRATION • Air for Zero and O2 Span. • Analyzed calibration gas mixture to span all readings except O2 NOVA ANALYTICAL SYSTEMS INC. www.nova-gas.com Suitcase Style (K) Cabinet

DESCRIPTION The Nova Model 7900P Series Heat Treat analyzers utilize a three channel high stability infrared detector for the simultaneous measurement of CO, CO2, and CH4 in exothermic or endothermic gas mixtures. In addition, the analyzer can be supplied with a fully compensated thermal conductivity cell for H2. O2 detectors can also be supplied for measuring either low (PPM) or percent levels of oxygen in the sample gas stream. Optional dew point is detected by a dielectic ceramic sensor and is available in standard and low ranges. All detected gases have a separate digital readout. Recorder...
