Digital EMS MY-EMS

single-enginefor aircraftfor ULM

Overview
Designed from the experience of three different full-featured engine monitoring systems, My-EMS delivers a modern EMS within a traditional round instrument format. It is intended for pilots and light aircraft builders who prefer classic gauge mounting while requiring advanced engine monitoring. The unit fits a 3-1/8" (80 mm) cut-out and accepts probe connections directly at the instrument rear, eliminating external interface modules. Customizable graphic and audio alarms provide timely alerts while reducing distractions during critical flight phases.
