Confused between EDM 350 and EDM 730? Here a comparison between the two to help you select the most suitable EDM for your needs and your aircraft.
Both these Engine data managers are manufactured by J.P. Instruments, USA, the EDM 350 is for experimental aircraft only.

Both these Engine data managers provide the aircraft maintenance crew and pilots with real time information pertaining to the engine of the aircraft. Both EDM 350 and EDM 730 monitor the aircraft engine from the moment the ignition is switched on. From that moment on, any anomalies are instantly brought to the pilot’s attention via audio-video alarms.

The EDM 730 is a fantastic piece of aviation technology that offers full-colour high-contrast graphics. It is easily installed (vertical or upside down or horizontal) and is considered to be amongst the most advanced and accurate piston engine-monitoring instrument.
