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.

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.

Good support when we called with particular questions with the initial setup. We liked the functions and the price.
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
