The DPI610E-Aero is a low cost yet flexible portable calibrator for precision leak testing of aircraft pitot static systems. Configured as a single channel unit for testing either altitude or airspeed parameters, it is fully self-contained with manual pressure and vacuum generation and venting facilities. Conversion to aeronautical units is provided and the instrument also includes leak and switch tests as well as other functions. The pneumatics system is the DPI610E-A limits both the maximum rate of climb and descent to protect connected delicate aircraft instrumentation such as Rate of Climb (RoC) meters. With a 5m length aero hose (6mm bore) and RoC meter attached with a total volume of 1 liter the maximum rate of climb is ± 6000 ft/min. Pressure fitting is a choice of AN4, AN6, Hansen or Staubli quick fit connection which includes an integral valve for letdown to ambient ground pressure conditions.This DPI610E-Aero Portable Aircraft Leak Tester (EDMO# DPI610E) has all pressure units, an AN4 output connector adapter, and Bluetooth is not required for operation.
