This articulating air-velocity probe uses Windows Mobile PDAs to display and datalog measurements. A thermal sensor is mounted on a telescoping shaft that incorporates technology to eliminate internal cabling. The AS-202A hotwire anemometer probe telescopes from 21 inches closed, out to 37 inches fully extended. The top 6 inches of the tip can be snapped straight out 180 degrees or ratcheted to 90 degrees. The articulating tip makes the probe ideal for reaching ceiling diffusers and ceiling filters without a ladder, according to the manufacturer. The probe connects to a mobile computer where air speed, temperature and volume flow may simultaneously be displayed and recorded. Mobile PC features include on-screen, work-flow instructions; test-site description and labeling; audio notes and averaging function.
