Particle size sensitivity was determined for two fast response aerosol mass monitors, the GCA RDM-101 and -301. Readings from the mass monitors were compared to gravimetric measurements of concentrations of known size monodisperse and polydisperse aerosols. An effective measurement aerodynamic diameter (EMAD), defined as the particle aerodynamic diameter at which the monitor indicated 50% of the gravimetrically measured concentration, was determined for each monitor. The EMAD was 1.3 +/- 0.1 ..mu.. for both monitors. The effect of particle size sensitivity on the estimation of respirable dust concentration is discussed.
