LEMAG® Electronic Cylinder Pressure Indicator / ECI

Product Overview

LEMAG ECI is an Electronic cylinder pressure indicator which improves engine uptime and lowers operating costs.

LEMAG ECI allows technicians to balance, fine tune and monitor auxiliary and main engines.   The Electronic cylinder pressure indicator offers reporting on performance for all large 2- and 4- stroke engines no matter if they are running on natural gas, LPG or HFO/MDO, as long as they are equipped with an indicator valve.
