Abstract

The invention provides a gas-sensitive detection device which comprises a detection cover and a sensor platform, a probe platform or an integrated platform. The detection cover comprises a cavity and a cavity shell, a sealing cover plate movably connected with the cavity shell is arranged on the upper portion of the cavity, the bottom of the cavity shell outwards extends to form a first connection portion used for being connected with the probe platform, the sensor platform or the integrated platform detachablely, and a gas incoming and outgoing device is arranged on the side wall of the cavity shell. By the gas-sensitive detection device and a using method thereof, the problem that gas-sensitive detection devices are complex to operate, low in compatibility and high in cost is solved.

Description

technical field [0001] The invention relates to a sensor detection device and its use method, in particular to a multifunctional detection device for gas sensors and gas sensitive raw materials and its use method. Background technique [0002] Gas-sensitive materials, that is, materials sensitive to specific gases, can quickly sense specific gases contained in the atmosphere, and convert the sensing state into electrical signals, so as to feedback the existence and concentration of gases through electrical signals; The raw material is packaged and externally connected with electrodes with specific functions, which is the gas sensor. At present, gas sensors are widely used in environmental monitoring, medical diagnosis, natural disasters, production safety and national defense and military industries. With the development of society and the improvement of people's living standards, everyone's requirements for the environment and safety are also constantly improving, which pu...
