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.

I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
EI tech support is the best.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
