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, EI's 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.

Specifications: 3.25” x 3.25” x 4.45” depth. Accuracy: 1/2%. Viewable in direct and indirect sunlight. Backlit for night operation.

The CGR-30P comes standard with a state-of-theart, fullcolor bar graph which assists with ROP/LOP leaning. Additionally, the bar graph has both “normalized” and digital readout screens. No other bar graph in the industry comes close to providing the number of options the CGR-30P offers. In addition to its bar graph, the CGR-30P can be configured to display a combination of the functions listed at the right.

Available Functions: RPM, MAP, EGT/CHT Bar Graph, Oil Pressure, Oil Temperature, TIT, Hyd Pressure, C.O., OAT, Vac., Fuel Pressure, Fuel Level, Fuel Flow, Fuel Remaining, Fuel Used, Fuel -GPS Related Data, Low Fuel Alarm, Recurring Fuel Alarm, Volts, Amps, Flight Timer, Tach Timer, Local Time, Zulu Time, Annuciators, Data Recording, USB Port, External Caution Lights, and More

Secondary Screen: This screen provides six additional functions to be displayed on the CGR-30P, as well as annunciators to display Main Screen alerts.

GPS Data Screen: This screen allows you to select between six sets of Fuel Flow, Fuel Remaining and GPS related data.

Fuel Quantity Screen: This screen displays the estimated Fuel Remaining for each tank, based on current Fuel Flow.

In addition to the “Main Screen”, the CGR-30P offers a “Secondary Screen”, a “Fuel Quantity Screen” and a “GPS Data Screen.” These additional screens give the CGR-30P flexibility not found in any other engine instrument.
