DESCRIPTION
The Nova 460 Series SO2 analyzers utilize a reliable microprocessor-based non-dispersive infrared detecter
specific to SO2. In operation, the internal sample pump draws the sample gas through the filter/ condensate trap, secondary filter, flow meter, and then on to the infrared detector. The detector output is digitally linearized and then displayed as percent or PPM SO2 on the digital meter. The output is also available as an analog or digital signal.
