TR-1-Ng Replacement Instrument

The TR-1-Ng is our 2′′ engine gas generator RPM instrument for use with turboprop and jet engines. This instrument has exceptional performance, reliability and features a design driven by our 38+ years of experience. If you need to replace or overhaul an old failing gas generator instrument, buy our TSO approved TR-1-Ng gas generator RPM instrument which was designed with the latest digital technology. We’re so confident you’ll love the performance, reliability and features of this instrument, we offer a three month money-back guarantee. If you don’t like it, send it back for a full refund.

The TR-1-Ng gas generator instrument was designed as a replacement for existing 2′′ gas generator RPM instruments. Depending on your current installation you may need to wire in aircraft power and ground. The instrument features a 210° analog arc, backlight with auto dimming and a digital display. The instrument’s faceplate will be custom built to match your aircraft’s limits (red/yellow markings).

The TR-1-Ng fits into a 2′′ standard round hole (MS28041-1A mount) and is 4.23′′ long (one of the shortest cases on the market). It is FAA Certified to TSO: -C43c, -C44c, -C45b, -C47a, -49b, -C55a and comes with an FAA 8130-3 Airworthiness Approval Tag.

We have a full line of turboprop instruments designed as a replacement for existing 2′′ instruments. For more information download the Download the TR-1 Brochure. If you are looking for a single, glass panel instrument to replace all of your 2′′ engine instruments take a look at our STC’d & TSO’d MVP-50T.
