With
the DataRAMTM, you'll never again have to wait
for laboratory results to assess whether airborne
pollutants have reached dangerous levels. The
DataRAM Real-Time Aerosol Monitor measures mass
concentrations of airborne dust, smoke, mists,
haze, and fumes and provides continuous real-time
readouts. Large capacity onboard data logging
capability lets you save concentration data
for future analysis. With optional accessories,
the DataRAM can also provide respirable, PM-2.5,
or PM-10 correlated measurements. For exposure
sampling or continuous unattended indoor air,
ambient, duct, or process monitoring, no other
aerosol monitor is as fast, accurate, and easy
to use as the DataRAM.
Designed
for High Sensitivity
A high-sensitivity nephelometric monitor, the
DataRAM samples the air at a constant, regulated
flow rate by means of a built-in diaphragm pump.
The DataRAM's light scattering configuration
is optimized for the measurement of airborne
particle concentrations, maximizing the unit's
sensitivity. The detected signal is processed
by state-of-the-art lock-in circuitry followed
by high-resolution digitization, achieving ultimate
detectability of atmospheric Rayleigh scattering
fluctuations.
The
Widest Measurement Range of Any Real-Time Particulate
Monitor
In addition to its high sensitivity, the DataRAM
has the widest measurement range of any real-time
aerosol monitor-from 0.0001 mg/m3 (0.1µg/m3
) to 400 mg/m3 . With a total span of almost
7 decades, the DataRAM is capable of effectively,
measuring mass concentrations of airborne particles
in industrial and ambient environments ranging
from exceptionally pristine to extremely polluted.
The instrument can also be used for atmospheric
visibility measurements over a wide range of
scattering coefficients. (0.00015 to 600 km
-1). The DataRAM's auto-ranging digital display
provides
both real-time and time averaged concentrations.
Exceptional
Long-Term Stability
The DataRAM incorporates several technological
advances which guarantee exceptional long-term
stability. Near infrared source output feedback
control provides drift-free operation and excellent
temperature stability. For either manual or
preprogrammed/automatic zeroing of the monitor,
an electronically controlled latching solenoid
valve diverts the entire filtered air stream
though the optical sensing stage in order to
achieve "zero" air reference. In addition,
instrument span checks (secondary calibration)
can be performed simply by turning a knob on
the DataRAM's back panel, which inserts a built-in
optical scattering/diffusing element into the
filtered air stream. On-screen diagnostic indicators
and automatic shut-off for low battery conditions
also help ensure the monitor's correct operation
and data storage.
Maintenance-Free
Operation
After passing through the optical sensing stage,
all the particles are retained on a HEPA filter.
Part of the filtered air stream is then continuously
diverted through and over all optically-sensitive
areas (lens, light traps, etc.) to form a continuous
air curtain which protects against particle
deposition. This design, in conjunction with
a highly reliable diaphragm pump, ensures
long-term maintenance-free operation. A membrane
filter (with special holder included) can be
substituted for the HEPA cartridge for gravimetric
and/or chemical analysis of the particles collected
downstream of the sensing stage.
Menu-Driven
Information Displays
In addition to the auto-ranging real-time concentration
readout,
the DataRAM provides users with a variety of
informational
displays on its 8-line LCD screen. Real-time
and date, time-
weighted average concentrations, elapsed run
times, and other
information are easily viewed by selecting the
appropriate screen
using a scroll-through menu. Operating parameters
and diagnostic
information displays can also be easily accessed
through the menu using only 6 keys on the front
of the instrument.
Integral
Large-Capacity Data Logger
The DataRAM has built-in large-capacity data
logging capabilities. Stored information includes
time and date, average concentrations, maximum
and minimum values over selected periods, STEL
concentration, and tagging codes. Logged information
can be retrieved either by scrolling through
the DataRAM's display or by down-loading to
an external device such as a personal computer
or printer.
Digital,
Analog, and Alarm Outputs
The DataRAM provides continuous digital output
(by means of an RS232C data port) as well as
analog output, and a switched
output for selectable high-level alarm with
a built-in audible signal.
Accessories
Expand Versatility and Enhance Accuracy
Several optional accessories are available for
use with the DataRAM for a wide range of sampling
applications. A cyclone precollector allows
respirable particle measurements. An omni directional
air sampling inlet (with or without a PM-10/2.5
head) is available for ambient monitoring. Isokinetic
inlet nozzles are available for duct sampling.
An in-line heater module allows accurate monitoring
of solid particles in high humidity/fog
conditions. A sample dilution accessory permits
elevated temperature and/or very high concentration
monitoring. To down-load data to a PC or laptop
any standard seial communications software package
(e.g. Microsoft WindowsTM 3.1) can be used.
Standard spreadsheet packages (such as Microsoft
ExcelTM, LotusTM, and others) can easily access
and analyze data log files transmitted to a
PC for review and archiving. A portable battery-powered
printer and cabling accessories are also available.
Standard
accessories included:
universal voltage battery charger, standard
HEPA filter cartridge, analytical filter holder,
PC communications software disk, digital output
cable, carrying case, and instruction manual

FEATURES
AND APPLICATIONS
The DUSTTRAK Aerosol Monitor is a portable, battery-operated,
laser-photometer that measures and records airborne
dust concentrations. Use it to measure aerosols
in a wide variety of environments, from offices
to industrial workplaces. Common applications
include:
Indoor Air Quality Investigations
Industrial Workplace Monitoring
Environmental Monitoring
Evaluation of Filters and Engineering Controls
Real-time Remote Site and Perimeter Monitoring
With the DUSTTRAK Aerosol Monitor, an easy-to-read
digital display shows real-time concentrations
in milligrams per cubic meter (mg/m³) while
data is simultaneously logged into memory. And
the DUSTTRAK has enough memory to record weeks
worth of data, even at one-minute intervals. You
can program start and stop times for unattended
data logging. The DUSTTRAK Aerosol Monitor executes
your instructions with microprocessor precision
and patiently waits for your return. Your precious
data is safely tucked away in lithium-battery-backed
memory. What do you do with all that data? When
you're ready, download the data from the DUSTTRAK
monitor to your PC and easily create custom graphs
using the Windows software included with each
instrument. You can illustrate how airborne particle
concentrations vary over time, and pinpoint hard-to-locate
time-of-day dependent IAQ (indoor air quality)
or industrial workplace problems. Print graphs
on a monochrome or color printer and use them
to make impressive reports or presentations. Overlay
other DUSTTRAK graphs or data from a TSI Q-TRAK
Plus IAQ Monitor or P-TRAK Ultrafine Particle
Counter to help identify suspicious patterns.
The
DUSTTRAK with analog and alarm outputs can now
be used in applications like site perimeter
monitoring, ambient monitoring, and other remote
monitoring applications. The analog output is
capable of providing a voltage signal that is
proportional to the displayed mass concentration.
The analog output has an output voltage range
of 0-5 VDC, with four user selectable ouput
scaling ranges. The alarm output with adjustable
setpoint can alert the user of upset or changing
conditions. This new feature allows you to program
a switch closure to occur at the aerosol mass
concentration value of your choosing. The alarm
setpoint is user-defined via TRAKPRO Data
Analysis Software. An on-board, audible alarm
beeps when the setpoint is exceeded and the
instrument's digital display alternates between
alarm ("AL") and the real-time aerosol
mass concentration reading.
