Model 354 Precision Airspeed Tester

Meriam Instrument introduces the Model 354 microprocessor-based Precision Airspeed Tester. This lightweight, portable unit provides reliable airspeed indicator testing and pitot system leak rate at the stroke of a key. It features an NIST traceable full scale accuracy of +/-0.05% FS, including all effects of linearity, repeatability, hysteresis, and temperature over the range of 23 to 122 F. The tester displays airspeed in knots, miles per hour (mph), or kilometers per hour (km/h), with resolution to the nearest tenth of a knot, mph, or km/h. Other features include user-selectable pressure units in inches or water at 60 F, inches of mercury at 0 C, PSI, or millibars.
