Calibration system for dust concentration monitoring device

The utility model provides a calibration system for a dust concentration monitoring device. The calibration system comprises an experiment module, a dust generating device, a dust filtering device, a to-be-calibrated dust concentration monitoring device and a reference dust concentration monitoring device, at least one dust source air inlet is formed in the cabin wall of the experiment cabin; an air outlet of the dust generating device is communicated with the dust source air inlet through a pipeline and is used for inputting one or more kinds of dust of different types into the experiment module through the dust source air inlet for monitoring; the dust filtering device is arranged in the experiment module and is used for reducing the dust concentration in the experiment module, so that the production test and calibration efficiency is improved; the at least one to-be-calibrated dust concentration monitoring device and the reference dust concentration monitoring device are respectively arranged in the experi
