Abstract
A multi-port calibration xture for the cross calibration of aerosol point sensors has been developed. The system was designed for comparative calibrations of instruments using differing measurement methods such as optical particle counters, aerodynamic impactors, etc. Four isokinetic sampling ports are attached to a laminar ow plenum such that all four sampling ports sample identical aerosol concentrations under identical ow conditions. Correlation and correction factors are applied to each instrument creating a standard method. This standard method can be applied to inter-compare and calibrate aerosol sensing instrumentation and/or to characterize the microphysical properties of a test aerosol. The performance of this xture has been demonstrated with a TSI 3321 APS, a GRIMM 1.109 and a MetOne OPC.
