Item # Model 481N4N7, Model 481N4N7, Carbon Monoxide Analyzer (infrared), ex-proof sensor housing with NEMA4 wall-mount control cabinet (two separate enclosures)


The Nova FLEXI-NOVA Series Platform has been designed for continuous gas measurements in applications and environments that are less intensive. Lab work, research, clean processes, pre-treated / pre-cleaned produced gases, and others, may benefit from the FLEXI-NOVA series.

Depending on application, some light-duty sample conditioning features may be available. For clean process measurements of percent-level CO gas by infrared detector.

All sensors / detectors are temperature-controlled or temperature-compensated for maximum analytical stability. Easy calibration using touch-screen controls. Serial Output Package allows connection & data-logging to personal computers via a choice of USB / RS-232 / RS-485.



Cabinets: Wall Mounted NEMA7 UL/CSA Class1 Div1 Explosion-proof sensor cabinet, with NEMA4 wall-mount control cabinet (two separate cabinets)
