1811HA-633

The Barfield 1811HA testers are portable, self-contained units, used for testing and calibrating aircraft pitot/static systems. The tester uses three analog instruments (Altimeter, Vertical Speed, and Airspeed) with the appropriate correction cards to perform aircraft leak tests or instrument calibrations. All 1811 series testers are configured with hand pumps and external pressure ports for supplying the necessary pressure and vacuum (no external power required) needed for on-board testing and calibration. The Barfield 1811 series of Air Data testers are very practical for new facilities or those with a limited budget. The unit includes two 25-foot hoses, a pitot mast adapter, a 2423F static port adapter kit and a pitot-static system videotape.
1811HA models come with an additional internal electric pump. The is also available with the DAS650 Digital Airspeed and DALT55 Digital Altimeter.
