Kurz - Model 2442 -Industrial HVAC Portable Flow Meter
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.
