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.
- Custom calibration (mapping) for unparalleled accuracy.
- Optional two open-collector (pull-down) for controlling external warning lights or props (0.1 Amps max).
- Optional ARINC 429 compatible via the BC-5 (contact EI Support for details).
- Available Bluetooth connectivity, great for remote fleet calibration and data downloads.

I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
. . . more functionality, easier install, and folks at Gulfcoast said your customer service is outstanding.

Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
