Two Oil Mist Detection Systems; Two Different Applications

Recognising that early detection of Oil Mist helps to safeguard personnel and equipment before a fire occurs, QMI developed two different systems for two different applications. The Engine system was traditionally used to measure Oil Mist particles inside the crankcase of a diesel engine and the Atmospheric system used to measure Oil Mist in any confined space, such as manufacturing test areas, LNG Carriers & Gas production platforms.

An Oil Mist Detection System is made up of a Monitor and one or more Oil Mist Detectors or Sensors.
