Automatic membrane dust sampling device and sampling analysis system trade

The utility model discloses automatic membrane dust sampling device and sampling analysis system trade relates to a dust sampler and a dust sampling analysis system. Membrane dust sampling device is moved in order to provide one kind certainly to its purpose, when using the device to carry out the dust sampling, can realize the automatic diaphragm of sampling of changing of 24h, has saved the human input to the sampling precision has been improved. The utility model discloses from moving membrane dust sampling device, include: time relay, move membrane mechanism and sampling head certainly, time relay with switch from moving membrane mechanism links to each other to control is from moving the frequency of operation of membrane mechanism, from move membrane mechanism with the sampling head corresponds the setting to update the sampling diaphragm to the sampling head. The utility model relates to an adopted the sampling analysis system of sampling device still includes sample analysor, display and PC host computer.
