Clean workshop cleanliness verification and detection device

The utility model relates to a clean workshop cleanliness verification detection device, which comprises a particle counter body and a storage device, the particle counter comprises a counting shell, a light path, a gas path intersected with the light path and a signal processing system connected with the light path, the gas inlet end of the light path of the particle counter is communicated with a gas inlet nozzle through a first vacuum pump, and the gas inlet end of the light path of the particle counter is communicated with the gas inlet nozzle through a second vacuum pump. A light path air outlet nozzle of the particle counter is detachably connected with the air inlet end of the second vacuum pump, and the second vacuum pump is communicated with the storage device. The device is simple in structure, can store a measured gas sample, can be used for secondary verification when needed, is expanded on the basis of real-time detection, and can be used for verifying the accuracy of a detection result again. 本实
