SAMPLER

The utility model belongs to the sampling detection new technology and discloses a single body sampling device. The breathing crawl of a human body is used as the driving force. The single body sampling device is provided with a variable quantity gas room and through a driving mechanism, causes a counting device to count the flowing quantity. And needed sampling elements are matched and the test is carried out. The single body sampling device changes a sampling device in China or foreign countries using a battery as the source motive power with the accurate measurement affected by factors such as the power consumption changing, etc. The single body sampling device fundamentally solves the tracking sampling of the extent of harm of the factory and mine harmful substance to workers and also enhances the accuracy for counting the flowing quantity. Simultaneously, the single body sampling device provides the explosion preventing detection facility for places easily getting burned and exploded.
