Model 3688-A Air Data Calibrator

Description:
  • The Model 3688-A Portable Air Data Calibrator by King Nutronics Corporation is a MIL-T-28800C qualified instrument that provides regulated static (Ps) and total (Pt) pressure/vacuum output, simulating altitudes and airspeeds for the purpose of testing aircraft altimeters, airspeed indicators, and rate-of-climb indicators. Regulated pressure/vacuum can also be supplied using in-Hg, m-Hg, in-H2O, psi, and millibar units, enabling laboratory standards, master gauges, and pneumatic recording devices to be tested and calibrated using the same equipment.
