Product Overview

TR-1 Features

Our TR-1 provides exceptional performance, reliability and features. If you need to replace or overhaul an old failing instrument, consider buying one of our TR-1s from a company which has been designing quality aircraft instrumentation for over 40 years. Purchasing our TR-1 is substantially less expensive than overhauling or replacing your old needle gauge. We’re able to make this offer with a money-back guarantee because we’re confident you’ll love the performance, reliability and features these instruments offer.

Standard two-inch round (MS28042-1A mount), 4.23″ long.
Rugged and reliable design (unlike many old needle gauges).
Optional RS-232 input and output port to interface with EEC’s, FADEC’s and other devices.
