HD-1004 Real-Time Personal Dust Monitor is a completely portable package that allows true breathing zone measurements and comprehensive
graph reporting. The product is designed for aerosol and dust monitoring for industrial Hygiene and Environmental air investigations. HD-1004 is
individually worn and offers immediate determination and data storage of airborne particulate concentrations in milligrams per cubic meter. The patent pending sensor design that allows the interchange of sampling heads for inhalable, thoracic and respirable separations. The in-line disposable
cassette allows the user to simultaneously collect filter samples for further
gravimetric or chemical analysis.
The signal processing electronics and microprocessor are enclosed in a
compact case that attaches to the individual’s waist. A real-time display
reports concentrations in milligrams per cubic meter. Statistics such as:
TWA, STEL, Max and Minimum can instantly be viewed on the display.
The internal user adjustable alarm can be preset to alert the user of approaching
threshold limits.
HD-1004 can be used for a variety of applications including lead, silica,
welding fumes, pharmaceutical and construction dusts. Accompanying
software provides management ready graphs and reports. HD-1004 is an
excellent OSHA survey compliance tool for determining worker exposure
to airborne contaminants, evaluating levels of respiratory protection, or
any application that requires immediate and accurate air monitoring of
lung damaging particles.
