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.

Customer Testimonials
Very happy with our new tachometer!
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
