- Page 2 AirSentry II Calibration Station Calibration Station The AirSentry II Calibration Station allows users to calibrate the AirSentry II IMS to a specific calibration stream concentration. An internal pneumatic diagram of the calibration station is included on page 9 for reference, if needed.
- Page 3 Note After installing the permeation tube, allow 24 to 48 hours elapse time prior to calibrating an AirSentry II IMS analyzer. This time allows for the permeation device to warm up and near its expected permeation rate. Most permeation tubes will have reached equilibrium five to seven days after installation.
- Page 4 Without measurement there is no control As an example, a 0 - 50 ppbv Amines analyzer would be span calibrated at 25 ppbv. The span calibration provides a correction factor to adjust the calibration curve appropriately. Because most users are sampling in a wet environment (where the RH > 5%), a wet span calibration is most appropriate.

Page 5: Calibration Procedure
The AirSentry II IMS was designed so that it can be easily calibrated by disconnecting it from its sampling location and moving it to the location of the calibration station. The AirSentry II IMS is then set on top of or next to the calibration station allowing the various utilities to be shared between the instruments. - Page 6 Without measurement there is no control Figure 4 AirSentry II IMS - Pneumatic Setup (With Calibration Station) 5475 Airport Boulevard +-303-443-7100 info@pmeasuring.com Boulder, CO 80301 +1-800-238-1801 www.pmeasuring.com +1-303-449-6870 Page 5...

Note The best way to set the CDA pressure to 5 psi is to connect the AirSentry II IMS via the Service Software. The Press CDA column, located on the Control tab, digitally indicates the CDA pressure in kilopascals.
