DESCRIPTION The Nova 480 Series represent Nova' s best value in continuous low range CO process analysis. This analyzer utilizes a long-life electrochemical ' fuel cell' sensor for the detection of CO 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 recorder output. The 480 can be supplied with sampling pump or pressure regulator to suit most applications. MODELS There are seven types of mounting configurations available : � 480N4 - Wall mounted NEMA4 ( IP65) enclosure rating � 480N4X - Wall mounted corrosion-resistant NEMA4X ( IP65) enclosure rating � 480N12 - Wall mounted NEMA12 ( IP52) enclosure rating � 480PM - Panel mounted, slides open for easy access � 480RM - 19" ( 483mm) rack mounted, on sliding rails � 480N7MC: Wall mounted NEMA7 UL/ CSA ex-proof with non-intrusive magnetic calibration, Class 1 Div 1 Group BCD � 480PMN7: Wall mounted NEMA7 sensor housing with panel mounted control cabinet ( two separate enclosures) SPECIFICATIONS Method of Detection : Customer replaceable electrochemical ' fuel cell' CO sensor.
