The following is a list of some of the advanced features of the 2000
i
-D:
●
PM
10
sample stream split into fine (PM
2.5
) and coarse (particles between
2.5 and 10 microns in size) fractions using a U.S. EPA-designed virtual
impactor.
●
Particulate matter is collected on two separate 47 mm diameter filters
simultaneously.
●
An active, volumetric flow control system maintains two constant
volumetric flow rates at the levels specified by the user (default of 16.7
L/min, split into 15.0 L/min and 1.67 L/min) by incorporating two
separate mass flow controllers, and one ambient temperature sensor and
one pressure sensor. Sampled volumes are reported in volumetric and
standard terms. The Sampler uses a reliable sample pump.
●
The temperature of each collection filter is maintained within 5 °C of the
outdoor ambient temperature by a continuous filter compartment
ventilation system.
●
The sampler uses standard 47 mm filters housed in convenient reusable
cassettes. These cassettes are mounted in a single-filter tray for easy
exchange and transportation to and from the sampling site.
●
Operational simplicity, performance audits and stored data retrieval are
made possible through an embedded microprocessor and menu-driven
software.
●
Interval data are stored every 5 minutes, and include the 5-minute
averages of the filter temperature, ambient temperature, ambient pressure
and average flow rate. Data storage continues during and after the
exposure of the collection filter. The Sampler has a capacity greater than
86 days of interval data (five minute logging with six data items).
●
A record of filter data is stored for each sampling event used in the
Sampler and includes all U.S. EPA-specified values such as error
condition flagging, and average temperatures and pressures. Filter data
records also include sampled volume in volumetric and standard terms,
and meteorological and analog input data averaged over the collection
period. The Sampler can store 32 filter data records.
●
The Sampler stores records of user input data every 30 minutes by
default.
●
Inputs received from external sources in analog voltage form are
converted to engineering units through user-defined formulas.
●
User input data storage rates and variables are user selectable.
