Harness The Power Of Portable
Measure Ventilation - Estimate Energy Savings - Building Troubleshooting
Overview
This application guide is much more than a product manual. It is also targeted at making you
knowledgeable as to how the measurement of carbon dioxide (CO
buildings better in order to save energy and solve problems. Its one thing to measure CO
however this book provides a study guide that will quickly give you the critical knowledge and a
competitive advantage in using CO
ventilation and building performance.

Page 3: Spot Check Ventilation Rates
Background The PT9250 not only measures CO Temperature but it also calculates the outside air ventilation rate in cfm per person based on the Battery power level is also displayed in the difference between inside and outside CO middle left portion of the display. - Page 4 OSHA. In buildings the CO concentration is than the 400 ppm level assumed by the PT9250. more an indication of ventilation. If a space feels (A difference of about 50 ppm will result in an uncomfortable, stuffy, or stale and the CO levels error of about 0.5 cfm/person in the calculation.)

7 Day – 15 minute sampling • Battery Life & Logging: The battery life of the PT9250 is 10 to 16 hours. As a rule you should have the PT9250 plugged into it’s charger whenever you are logging concentrations for extended periods of time. -

Calibration gases, tubing and regulators are available from AirTest. Zero & Span Calibration: Typically, drift of the PT9250 is on the zero adjustment of the sensor. The sensor generally should not require span adjustment. If performing both types of calibration the zero calibration should be performed first. - Page 9 Control: If outside levels are at or near 400 ppm and the activity level is close to office type activity then AirTest has just release an easy to use software the CO /cfm-per-person conversion chart in tool that allows you to compare the cost of Section 3 of this guide can be used.
