AIRSPEEDS |
Sigma Tek's precision airspeeds are original equipment on a variety of aircraft and over 144,000 have been delivered worldwide.
These proven instruments are totally manufactured in-house by Sigma Tek. They incorporate a proprietary sensing element designed to resist overpressure and to provide for automatic temperature compensation. The true airspeed model includes a sub-dial the pilot sets to coincide the outside temperature with the flight altitude for immediate true airspeed reference.
Sigma Tek's highly accurate and durable airspeeds can be calibrated in either knots, mph, or kilometers, and customized with a choice of speed ranges, dual scales, range marks, and internal lighting.
