Calibration
The Model 5030
i
is an instrument that can make accurate mass
concentration measurements of PM
10
, PM
2.5
and PM
1.0
. However, with all
electronic instruments, the accuracy of the measurements depends on
proper calibration.
In general terms, calibration, also called standardization, is the process that
establishes the relationship between sensor output signals and the
parameter the operator is attempting to measure. The 5030
i
instrument
uses sensors that measure temperature, humidity, pressure, and radiation.
This chapter describes the procedures for performing the necessary sensor
calibrations. This chapter is also a follow-up to the Acceptance Testing
outlined in the “
Installation
” chapter and a continuation of the menu
display descriptions in the “
Operation
” chapter.
Each instrument is calibrated and tested for accuracy at the factory. The
mass calibration is conducted with a set of NIST-traceable mass calibration
foils. The radiation detector is calibrated against certified check sources for
beta and alpha emissions. The temperature, relative humidity, pressure and
flow rate are all calibrated against NIST traceable standards.
It is recommended that the instrument be calibrated once per year and
encounter quality checks on a periodic basis in accordance with the users
specific quality assurance project plan. For example, volumetric flow checks
on a two-week basis are common in some air monitoring agencies and with
full-scale quarterly audits for flow and mass. The
Quality Assurance
Handbook for Air Pollution Measurement Systems,
published by the U.S.
EPA, Research Triangle Park, NC 27711, can be consulted for detailed
quality assurance guidelines.
Optional mass transfer standards are available from Thermo Fisher
Scientific for performing an annual mass calibration. However, additional
specialized equipment is needed to calibrate the Model 5030
i
for
temperature, relative humidity, barometric pressure, and volumetric flow.
The following equipment should be used:
●
A thermistor or thermocouple thermometer capable of measuring
ambient temperatures in a range of –20 to 50 °C, readable to the
Frequency of
