Item # Model 410N7MC, Model 410N7MC Process Oxygen Analyzer, in Explosion-proof cabinet, Class 1 Div 1 Group BCD

The Nova 410 Series represent Nova's best value in continuous process Oxygen analysis. This analyzer utilizes a long-life electrochemical 'fuel cell' sensor for the detection of O2 in process gases. The sensor produces a small millivoltage output which is directly proportional to the Oxygen detected. The output is then amplified and displayed on a digital readout meter and can also be sent to an optional recorder output. The 410 can be supplied with sampling pump or pressure regulator to suit most applications.

Cabinet: Wall Mounted NEMA7 UL/CSA Explosion-proof with Non-intrusive Magnetic Calibration, Class 1 Div 1 Group BCD. Availability depends on application and environment. Sample conditioning options not available with this cabinet style.
