DESCRIPTION The Nova 481 Series Carbon Monoxide analyzers utilize a simple and reliable microprocessor-based non-dispersive infrared (NDIR) detecter specific to CO. 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 the filter/condensate trap, secondary filter, flowmeter, and then on to the infrared detector. The detector output is digitally linearized and then displayed as percent or PPM CO on the digital meter. The output is also available as an analog or...
