Electronic Cylinder Pressure Indicator (ECI)

The LEMAG ECI is an electronic cylinder pressure indicator which advances engine uptime and lowers operating expenses as it allows technicians to balance, fine tune and monitor auxiliary and main engines. The ECI allows to report 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.

The ECI is easy to use even while using gloves. The ergonomic handheld unit shows measurements on a large colour display enabling confirmation on site in real time that the measurement process was successful. The results can be sent to a PC and analysed with the included software, or transferred to the superintendent for additional comparison with historical or reference data. The step-by-step graphic instructions for various tasks, as well as easy-to-understand menus, makes LEMAG ECI easy to handle, also for new operatives.
