Abstract/Summary
Accurate measurement of indoor and industrial contaminants generated by current technology and emerging nanotechnology is an important component of occupational and environmental hygiene practice. Direct reading instruments are frequently used to determine the effectiveness of engineering controls and the quality of indoor air. The study assesses the effects of temperature, humidity, and concentration on commercially available direct-reading instruments. Other concerns are the uncertainties associated with standard factory calibrations. The results of this study are revealing limitations and opportunities for improvements in current instrumentation and will be valuable in choosing appropriate direct-reading instruments for use in field evaluation of industrial and other ventilation systems.
