Visit, www-tisch-env.com, to download calibration worksheets. The calibration worksheets
allow the user to input the data and automatically make the calculations. The manual
calculation method is described in the following sections for your reference, however, it is
highly recommended to download the calibration worksheets.
Calibration Procedure
The following is a step by step process of the calibration of a TE-5170 Mass Flow Controlled
Total Suspended Particulate High Volume Sampling Systems. Following these steps are
example calculations determining the calibration flow rates, and resulting slope and intercept for
the sampler. These instructions pertain to the samplers which have air flow controlled by
electronic mass flow controllers (MFC) in conjunction with a continuous flow recorder or a
manometer. This calibration differs from that of a volumetric flow controlled sampler.
The Total Suspended Particulate samplers (TSP) are also referred to as lead samplers as this is
another use for these instruments. The instruments are also suitable for capturing large
particulate and heavy metal particles. Air monitoring studies that are concerned with smaller
respirable particulate will call for the use of PM-10 particulate samplers. The TSP samplers have
a wide range of acceptable air flow operating limits, i.e., 1.10 to 1.70 m3/min (39 to 60 CFM).
A mass flow controller will sense a decrease in air flow as particulate is collected in the filer
media and increases the voltage to the blower which increases the blower speed in order to
maintain the set flow rate.
The attached example calibration worksheets can be used with a TE-5028 Variable Orifice
Calibrator which uses an adjustable or variable orifice.
One example calibration sheet is attached to this manual. To download the electronic
spreadsheet, please visit www.tisch-env.com. It is highly recommended to download the
electronic spreadsheet and use the spreadsheet features to complete calculations,
calibration worksheets can be found by visiting www.tisch-env.com.
