The MD215 is an economical replacement for legacy 2-inch counterdrum altimeters, commonly found on turboprop and advanced light-to-heavy business jet aircraft.
The MD215 combines the time-tested familiarity of a mechanical display with the reliability and value of electronic pressure sensing and servo-driven motors. It is a perfect form and fit replacement for traditional 2-inch counterdrum products, which can be expensive to repair or replace.
The optional internal battery provides one hour of emergency operation in the event of power loss to the instrument.
