Electronics International CGR-30C Primary Engine Monitor

The CGR-30C is a technologically advanced, STC’d and TSO’d primary replacement instrument designed to consolidate up to 16 traditional gauges into a single, sleek 3-1/8” digital display. This all-in-one instrument allows you to remove entire clusters—including Oil Temperature/Pressure, Fuel Pressure, Fuel Level, RPM, and Manifold Pressure—while providing reliable, world-class engine and system monitoring. Its full-color digital display offers clear, easy-to-read strip and arc gauges for critical parameters, along with pinpoint digital readouts, giving pilots an intuitive view of engine and system performance at a glance.

The CGR-30C includes 6 annunciators tied to external switches, an optional alternative Main Screen configuration with MP and RPM arcs, and a Secondary Screen to display up to six additional primary or secondary functions. Red and yellow range annunciators alert the pilot of any limit violations with blinking notifications. The system also supports custom checklists, allowing up to 50+ checklists to be uploaded via USB for preflight, inflight, and post-flight procedures. Flight data is easily recorded and downloaded via USB in a comma-delimited format compatible with Excel, and the Engine Data Converter (EDC) simplifies installation with only two wires running to the back of the instrument (standard 8-foot wire included). With the CGR-30C, you gain a modern, compact, and highly reliable engine monitoring solution that replaces multiple analog instruments, improves situational awareness, and streamlines your cockpit.
