Abstract:A new calibration method for the standard optical particle counter was introduced. According to the stepwise traceability chain of optical particle counter —condensation nucleus counter —aerosol electrometer, the count value of optical particle counter could be traced to the current standard. A complete traceability system was formed. The results show that this method can not only evaluate the counting efficiencies of optical particles in different radius ranges, but also solve the calibration problem in different flow rates.
Keywords: optical particle counter; traceability; counting efficiency; flow
