Abstract
An apparatus for use with residential, commercial and industrial HVACR air duct systems and equipment, providing a means to quickly, easily and accurately measure and/or test air properties within functioning HVACR systems without having to drill a hole into the duct or equipment wall(s) each time the unit is serviced. The apparatus generally includes a mounting flange for attachment to an air duct or other equipment of an HVACR system and an access port including an opening for insertion of a probe therethrough for taking measurements; a cap is also typically included for sealing the access port during periods of non-use. The opening of the access port is centered and placed over a small hole created by a service technician in the wall of the air duct.
