A Theoretical and Laboratory Evaluation of a Portable Direct-Reading Particulate Mass Concentration Instrument,

摘要

A study of the design,construction,performance,and theory of operation of the RDM 101, a prototype instantaneous dust mass concentration monitor. Laboratory performance was judged from the results of coal dust measurements and comparisons in the NIOSH dust chambers. Simulated field performance results are presented from tests involving exposure of the instruments to environmental extremes. An attempt is made to realistically estimate the overall usefulness and applicability of the RDM 101to the characterization of particulate inhalation hazards in the industrial environment.
