1811D405

The Barfield 1811D is an inexpensive, portable, self-contained field tester. It is ideal for leak testing aircraft pitot and static systems or on-board testing of altimeters and airspeed indicators. The tester uses two analog or digital instruments (Altimeter and Airspeed) to perform aircraft leak tests or instrument calibration checks. All legacy 1811 series testers are configured with hand pumps and external pressure ports for supplying the necessary pressure and vacuum needed for on-board testing. The Barfield 1811 series pitot/static testers are very practical for new facilities or those with a limited budget. The unit includes two 25-ft. hoses, a pitot mast adapter, and a 2423F static port adapter kit.
