Sampling probe and monitoring system

The utility model discloses a sampling probe and a monitoring system, and belongs to the field of pollution source monitoring. Comprising a pipeline structure, a filter and a sampling structure, the sampling structure is provided with a sampling chamber, the pipeline structure is connected with the sampling structure so as to provide sample gas for the sampling chamber, and the filter is arranged in the sampling chamber; the reverse blowing assembly is arranged on the sampling structure and is used for reverse blowing of the sampling structure; the calibration assembly comprises a calibration structure and an exhaust structure, the calibration structure is arranged on the side, close to the pipeline structure, of the sampling structure so as to provide standard gas for the sampling structure and filter the standard gas through the filter, and the exhaust structure is arranged on the sampling structure so as to transmit the sample gas or the standard gas from the sampling cavity to the exhaust structure.
