    Specification :

    The Nova 470 Series CH4 analyzers utilize a simple and reliable microprocessor-based non-dispersive infrared detector specific to CH4. 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 CH4 on the digital meter. The output is also available as an analog or digital signal.
