JPI EDM-830, New in the box. Never installed. Never powered up. Four cylinder unit but more probes can be added to make it a six cylinder. The EDM-730/830 revolutionizes engine monitoring by the integration of brilliant full color graphical LCD display with the extremely popular EDM 700/800 series functionally and yet reduces the package size to the smallest on the market! The EDM-730 packs more features, functionality, and information onto its large full color screen than any other monitor available and features larger characters for easier reading. Oil pressure has also been added to the entire EDM series line. Mounting is a breeze due to its standard 3-4/8" format, and because it can be mounted in either portrait or landscape orientation, thus accommodating virtually any panel configuration. Depth behind the panel is an amazing 2-1/2". The unit is "Plug and Play" compatible with existing EDM-700/800 units. Full Color LCD Display: More Graphics Large digits for easy reading. Full color parameter range markings. Annunciation of exceedances. More information without "page swapping" FAA STC/TSO approved.
