DESCRIPTION The Nova 309 Series Portable Flue Gas Analyzers have been designed for accuracy, reliability, and ease of use and service. The 309 uses a long life electrochemical O2 sensor and a solid state infra red CO2 detector, both of which respond quickly to O2 and CO2 present in the flue gas sample. In operation, a built-in sample pump draws in the flue gas sample through the S.S. probe, 12 ft sample hose, condensate removal filter, secondary filter and flow meter then on to the O2 sensor and CO2 detector. The detected gases are displayed on separate LCD digital meters which have a switchable...
