G3620a/G3620p Stack Gas Oxygen Analyzing System
Brand: Green Instruments A/SThe G3620 Stack Gas Oxygen Analyzing System provides data to help control the fuel-air ratio in the burner. The system is installed directly in the stack close to the boiler, which provides real-time, wet oxygen measurements under actual flue gas conditions. This means that the sample is analyzed in situ without being passed through vulnerable sampling lines.
