The Barfield 1811D is a, 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.
Version1811D-403has an operating range of 60-420 kts and 50k feet.
