The Nova 420 Series CO2 analyzers utilize a simple and reliable microprocessor-based non-dispersive infrared detector specific to CO2. The detector pulses an infrared beam of light through the sample tube, without the need for a mechanical chopper. In operation, the internal sample pump draws the sample gas through a filter, flow meter, and then on to the infrared detector. The detector output is digitally linearized and then displayed as percent CO2 on the digital meter. The output is also available as an analog or digital signal.Cabinet: NEMA 4 cabinet with Hazardous Area Purge System; available for Class 1 Div1 & Div2 hazardous areas.
