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.

  • Optional two open-collector (pull-down) for controlling external warning lights or props (0.1 Amps max).

Simple and Easy.

Aaron H. from Washington
Cessna 140

The CGR-30P is working great and it’s an outstanding addition to our avionics package.

Charles J. from Idaho
PA-28-181

My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.

Scott N. from Montana
Cessna 182A Skylane

The display is large and clear. The functions are simple and easy to use. Great purchase decision.

Stephen J. From Texas
Beechcraft Bonanza K35

We’ve worked with EI for years and love the product and support always received. Quality & dependability.

Tammy B. from North Carolina

Nice unit. EI is the best!

Mark H. from Arizona

Met all my requirements; great support.

James Q. from Texas
Falco F8L

Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.

Nathan V. from Alaska
Cessna 172C

Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.

Larry K. From Kansas
Piper PA-28-181

I like how the kits ship with everything needed for install and the wire labeling was very helpful.

Nathan V. from Alaska

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.

David M. From South Carolina
Cessna 182J Skylane

We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
