Odor concentration monitoring device with double-sensor cross calibration

A double-sensor cross-calibration odor concentration monitoring device belongs to the technical field of gas monitoring and comprises an aluminum alloy shell, a gas inlet joint and a gas outlet joint which are mounted on the aluminum alloy shell, and a signal acquisition board mounted in the aluminum alloy shell, and two metal oxide sensors are welded on the signal acquisition board. The two metal oxide sensors are respectively a first metal oxide sensor and a second metal oxide sensor. The first metal oxide sensor and the second metal oxide sensor have good response to the malodorous gases, but the malodorous gases focusing on response are different. The utility model has the following beneficial technical effects: after the two sensors are used for cross calibration, the device can better adapt to the measurement of malodorous gases with different components and concentrations, the measurement result is more accurate, and the adaptability is stronger. 双传感器交叉校准的臭气浓度监测装置，属于气体监测技术领域，包括铝合金壳体、安装在铝合金壳体上的进气口接头和出气口
