indicators and other avionic instruments.
Model 3688-A
Air Data Calibrator
- 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.
- Enhanced accuracy RVSM compliant test set regulates pressure/vacuum from 0 to 32 in-Hg for Ps and 0.5 to 110 in-Hg for Pt.
- Accurate: ±0.002 in-Hg for Ps and ±0.002 in-Hg for Pt from 0.5 to 42 in-Hg (±0.004 in-Hg for Pt from 42 to 110 in-Hg).
Model 3719
Air Data Test Set
- Designed to provide regulated static (Ps) and total (Pt) pressure/vacuum outputs to simulate altitudes and airspeeds (Qc) in avionic instruments.
- Wide operating range: Simulates altitude from -1870 to 100,000 feet and airspeed from 20 to 1,000 knots (0 to 3.0 Mach).
- Accurate: ±0.002 in-Hg for Ps, ±0.004 in-Hg for Pt.
