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, percent-level O2 gas. This sensor utilizes a paramagnetic measuring cell and powerful selenium cobalt magnet assembly to make use of the principle that oxygen is drawn into a magnetic field, thereby offering a method of detection that is very specific to oxygen. Sample dew point should be at least 5°C (9°F) below lowest sample temperature.

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: NEMA7 Explosion-proof sensor cabinet for Class1 Div1 areas, with NEMA4 wall-mount control cabinet for non-hazardous areas (two separate cabinets)
