Flue Gas Oxygen & Humidity Analyzer

Gasboard 3050

Gasboard-3050 the Humidity & Oxygen Analyzer uses the principle of ceramic zirconia to measure the oxygen content and the content of oxygen and water (gaseous) mixed gas. According to the functional relationship between the oxygen content, the content of oxygen and water (gas) mixture and the sensor output signal, the humidity value and oxygen concentration value are calculated, and the humidity and oxygen concentration signals are output, which can provide an accurate basis for environmental humidity monitoring.

Gasboard-3050 features high accuracy, strong stability and long service life. It is a type of removable oxygen & humidity analyser, providing an ideal flue gas monitoring solution used in the condition of high temperature and humidity. It meets the technical requirements of online continuous flue gas emission monitoring system in regulation.
