Abstract In order to achieve the calibration of the standard diaphragm in ambient air monitoring, the calibration process of the standard diaphragm is standardized, including visual inspection, reduced mass, area, mass per unit area, etc.. Put forward the calibration method of the standard diaphragm will calibrate diaphragm with a single or a combination of the n E2 level weights compare get reduced mass on measuring instrument, the measurement area in the image measuring instrument, and then calculate the standard diaphragm mass per unit area, it is used to calibrate the continuous automatic monitoring equipment of ambient air particles and provide a basis for measuring the accuracy of the automatic monitoring of ambient air particles.
