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

Works great, super install.

Orie I. from Indiana
Bell 206

Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.

Phillip B. from Oklahoma
Cessna 210N Centurion / Turbo Centurion

Love my new engine monitoring system.

Tyler P. from Alberta, Canada
Cessna 185F

Easy installation, lightweight solution. It looks good and is easy to use.  [I chose E.I. because] I needed to replace my old Hobbs meter.  This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.

Thomas M. from Arizona
Rutan Model 61 Long-EZ

Great products and very clear install.

John W. from North Carolina
PA-12 Piper

Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.

Eric O. from Oregon
Cessna 150F

Excellent Service, superb product.

Steven N. from Colorado

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

Met all my requirements; great support.

Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
