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.

Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.

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.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.

After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
Good to go! Excellent instructions and easy install. Outstanding instrument!
You folks do a great job. Keep up the good work.
