Item # 7200 Series, Continuous Flue Gas Analyzer - 7200 Series



The Nova Model 7200 Series Flue Gas Analyzers are specifically designed for use on the flue gases from combustion processes burning gaseous fuels such as natural gas. These analyzers can measure sample gases from oil- or coal-fired processes with the addition of a Model 7240 heated sample filter. Optional dual or multi-point sequencers allow analysis of multiple points using one analyzer.

Sample gas is drawn into the analyzer from the sampling probe or heated filter, then pumped through a condensate removal system. Next, the dried sample gas is filtered again and flows through a PTFE liquid block, flow meter, then on to the gas detectors. The readings are locally displayed and also sent to 4-20mA recorder outputs.

Can be configured to measure a choice of the following gases:
  • Oxygen O2
  • Carbon Monoxide CO
  • Carbon Dioxide CO2
  • Sulfur Dioxide SO2
  • Nitric Oxide NO
  • Nitrogen Dioixde NO2

(choice and availability of sensors/detectors may depend on application & range)
(choice and availability of ranges may depend on application & sample gas)
