Item # Model 412N7MC, Model 412N7MC Paramagnetic Oxygen Analyzer, Wall Mounted NEMA7 UL/CSA Explosion-proof with Non-intrusive Magnetic Calibration, Class 1 Div 1 Group BCD


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.

Cabinet: NEMA 7 ex-proof cabinet, Class 1 Div 1 Group BCD
