CGR-30P Color Engine Monitor

EI is proud to introduce its CGR-30P, the best engine monitor available in the industry. The CGR-30P was designed to replace your aircraft’s tachometer. In addition to replacing your tachometer, the STC’d CGR-30P will replace MANY of your existing primary instruments. Because the CGR-30P is installed in a standard 3-1/8” hole, it doesn’t protrude from your panel or cover adjacent instruments. This gives the CGR-30P a distinct advantage over the competition because it seamlessly integrates into your panel, is easy to install and is the perfect size to fit into any aircraft panel.

FAA Approved Primary Replacement

  • Primary Replacement STC’d, TSO’d & PMA’d
  • Remove your old engine instruments, including RPM, Manifold, EGT/CHT, Fuel Level, Oil Pressure and more!
  • Upgrade your aircraft panel with the best engine analyzer available.

Easy To Install

  • CGR-30P fits into your existing 3 1/8″ hole (remove your old tach).
  • Engine Data Converter (EDC) accepts all inputs. Only 2 wires run to the back of the instrument.

Accurate, Dependable & Easy To Use

  • Electronics International consistently has been a leader in digital engine instrumentation since 1979.

Data Recording of Every Flight

  • All monitored functions are stored up to three times per second.
  • Up to 1,500 most recent flights stored, downloaded via a USB port.
