MGL Avionics


MGL Avionics

The E1 universal engine monitor combines in one compact 3 1/8” format instrument all that is needed to monitor most smaller aircraft engines from two-stroke ultralight engines to medium sized four strokes such as from Rotax, Continental and Lycoming. Most automotive engine conversions can benefit from the use of the E3 engine monitor.

The E1 can measure up to 4 EGT/CHT channels, a universal RPM input, a universal temperature sender input, a universal pressure sender input and the aircraft’s supply voltage.
