August 3, 2007 — GrayWolf Sensing Solutions of Trumbull, Connecticut, has introduced an articulating air velocity probe that utilizes Windows Mobile PDAs to display and data-log measurements.
A thermal (“hotwire”) sensor is mounted on a telescoping shaft that incorporates patented technology to eliminate internal cabling, says the company. The AS-202A hotwire anemometer probe telescopes from 21 inches (53 cm) closed, out to 37 inches (94 cm) fully extended. The top 6 inches (15 cm) of the tip can be snapped straight out at 180 degrees, or may be ratcheted to 90 degrees (also to 45 degrees for storage).
The articulating tip makes this probe convenient for reaching ceiling diffusers and ceiling filters without a ladder. An optional telescopic extension rod (186 inches, 472 cm extended) is also available for even greater reach. This makes the probe well suited for indoor air quality, heating and ventilation, thermal comfort, industrial hygiene and other applications
The probe connects to a mobile PC where airspeed, temperature and volume flow may simultaneously be displayed and recorded. The probe also plugs into Windows XP and Vista notebook computers, tablet computers, desktops and other platforms that are compatible via GrayWolfs WolfSense application software.
GrayWolf also offers add-on software modules for duct traverse and laboratory fume hood face velocity measurements. For more information, see the GrayWolf Web site.
