1.1 Description
The HiVol 3000 Particulate Sampler provides a flexible platform for sampling
of PM
10
, PM
2.5
or TSP particulate and for monitoring basic meteorological
parameters. The sampler is microprocessor based and features internal data
logging of flow and meteorological parameters.
The HiVol 3000 is designed to operate from a mains power supply. See Section
2 and 2.4.1 for important power connection details.
The HiVol 3000 incorporates ambient temperature and pressure sensors, which
are used to automatically maintain a constant volumetric flow-rate of typically
67.8 m
3
/h through a rectangular filter mounted in a cassette-style filter holder.
The HiVol 3000 includes the facility to monitor wind speed and direction, using
an optional external wind sensor. Wind speed and direction data are averaged
and stored in internal memory, and may be used as triggers for conditional
sampling.
The HiVol 3000 also has the ability to be remotely triggered by an optional
external sensor or instrument. The trigger signal can be used for remote control
or conditional sampling.
The HiVol 3000 also incorporates a time clock and programmable timer
enabling multiple times based sampling programs to be configured.
The HiVol 3000 internal data logger stores time based data averages at user
selectable intervals. The data includes date and time stamp, flow-rate, total
sample volume, average temperature, barometric pressure, and either wind
speed and wind direction or rain-fall information. Data values stored in the
HiVol may be downloaded via the RS-232C serial port.
The HiVol 3000 is extremely quiet (see Appendix A) allowing it to be used in
residential sampling locations to assess human exposure to particulate matter
(PM), and is housed in a weatherproof enclosure for outdoor sampling in a
range of environments. See Appendix A for typical noise levels.
