A Preliminary Study of the Main Factors Influencing the Accuracy and Efficiency of Dust Measuring Instrument Calibration
As an important tool to monitor the degree of particulate matter pollution in ambient air,dust measuring instrument is widely used in disease control,environmental protection and industrial and mining enterprises.In or-der to ensure the accuracy and reliability of its quantity value,it is necessary to carry out regular metrological verifi-cation or calibration.In order to improve the accuracy and efficiency of verification or calibration,this paper discus-ses several main influencing factors,such as instrument placement,instrument coefficient setting,dust rod quality,dust control mode,dust concentration stability time,etc.
