The Model 2442 has been specifically designed for HVAC Applications, such as air velocity traverses, air balancing and other tasks. It has a unique flexible “gooseneck” section between the sensor element and the sensor support, as well as an easily extendable telescopic wand which allows measurements at the ceiling height. The “gooseneck” section can be bent to 90° so that the user can orient the sensor element perpendicular to the air velocity direction when making traverses of air supply grates or open area. The Model 2442 uses the same “CD” sensor used for the Model 2441, except that it is mounted into a 3/8″ diameter sensor window/support. The sensor is completely protected when the telescopic, four-segment wand is collapsed. The telescopic wand is 47″ long when fully extended.
