1. DESCRIPTION OF THE MICRODUST pro
1.1 Introduction
Airborne particulate matter
can be found in the
atmosphere in the form of
dust, smoke, fumes, pollen,
and other aerosols. Major
sources of particulate in the
urban and working
environments include
combustion, materials
processing, manufacturing,
energy generation, vehicle
engine emissions, and
construction.
Particulate matter is
responsible for reduced
visibility, the spread of
contamination, inhalation of
toxic substances and low
worker productivity. It is
also recognised as a
contributory factor to many
medical conditions
including asthma, bronchitis
and lung cancer.
Traditional gravimetric methods of dust measurement require a significant
sampling period and are not suited to the evaluation of concentration trends
in real-time. The MicroDust pro is an ideal survey instrument for the
assessment of real-time particulate concentration in mg/m 3 . It is totally
portable and suitable for both fixed site and general survey applications. From
firmware Version 06, a user selectable analogue output and alarm are
provided that can be connected to external logging devices.
Accurate and repeatable dust concentration measurement is achieved using
proven forward light scattering techniques. The MicroDust pro offers
graphical presentation of concentration trends, internal data logging as
standard, simple and clear user interface and digital calibration methods to
suit any dust sampling scenario.
The WinDust pro Windows
TM software package supplied with this
instrument has been developed to make the downloading and presentation of
data as simple as possible. In addition, it offers a PC real time display of
particle concentration with a scrolling graph.
