DESCRIPTION The Nova 302 Series Portable Flue Gas Analyzers have been designed for accuracy, reliability, and ease of use and service. The 302 uses a solid state infra red detector which responds quickly to 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 CO2 detector. The detected CO2 is displayed on an LCD digital meter which has a switchable backlight for use in dark areas. The 302 can optionally indicate net stack temperature ( 302-T) for doing fuel efficiency calculations. The temperature sensor is built into the sampling probe. Efficiency charts for each fuel are provided. A rechargeable battery provides enough power for about 8 hours of continuous operation and the analyzer can be used while it is being recharged. A red LED tells when to recharge and a green LED verifies that it is receiving recharging power. The recharger is included.
