Item # 7200 Series, Continuous Flue Gas Analyzers


The Nova Model 7200 Series of flue gas analyzers are specifically designed for use on flue gases from combustion processes burning gaseous fuels.  The 7200 series analyzers can measure sample gases for oil or coal fired processes with the addition of a Model 7240 heated sample filter.  The 7200 can also measure flue gases in the presence of acidic or corrosive samples through the use of sample pre-conditioners.

Sample gas is drawn into the analyzer from the sampling probe heated filter or sample pre-conditioner, then pumped through a condensate removal system. Any condensate formed is collected then automatically purged.  Next, the dried sample gas is filtered again, then flows through a pressure regulator, PTFE liquid blocker, calibration gas valves, low flow switch, flow meter then on to the gas detectors.  An optional vacuum switch at the pump inlet warns if the pre-filter is becoming plugged up.

The 7200 Series analyzers are available in any combination of O2, CO, CO2, NOx (as NO or NO + NO2), SO2, or combustibles, with separate digital readouts and outputs for each.  Special sampling probes are available for high temperature applications up to 3200°F (1760°C).  The 7200 Series is multi-sample point capable (consult Nova).
