GENERAL CALIBRATION REQUIREMENTS
PM10 High Volume Air Samplers should be calibrated:
1. Upon installation
2. After any motor maintenance
3. Once every quarter (three months)
4. After 360 sampling hours
"Note" for supplemental guidance reference EPA's Quality Assurance Handbook
Section 2.11 also Appendix J located at end of this manual.
The two types of calibration kits available for PM10 High Volume Air Samplers are the TE-5025 and
The TE-5025 utilizes five resistance plates to simulate various filter loading conditions. The TE-5025
calibration kit includes: carrying case, 30” slack tube water manometer, adapter plate, 3’ piece of
tubing, TE-5025A orifice with flow calibration certificate, and 5 load plates (5,7,10,13,18).
The TE-5028 is the preferred method to calibrate PM10 High Volume Air Samplers. It simulates
change in the resistance by merely rotating the knob on the top of the calibrator. The infinite resolution
lets the technician select the desired flow resistance. The TE-5028 calibration kit includes: carrying case,
30” slack tube water manometer, adapter plate, 3’ piece of tubing, and TE-5028A orifice with flow
Each TE-5025A and TE-5028A is individually calibrated on a primary standard positive displacement
device, which is directly traceable to NIST.
** It is recommended by USEPA that each calibrator should be re-calibrated annually for
accuracy and reliability.
