testo 350 MARITIME - Portable Emission Analyzer for Diesel Ship Engines

0563 3503
  • With DNV and NK certificate 
  • Ready to measure after 2 minutes
  • Simple and accurate testing with the emission measurements quickly seen on the large, back-lit display
  • Determination of the fuel sulphur content by means of SO2/CO2/ ratio according to MEPC 184 (59)
  • The testo 350 MARITIME is the world’s first portable emission analyzer for diesel ship engines approved for MARPOL Annex VI and the NOx Technical Code.  Built to meet the demands of maritime conditions, it measures O2, CO, and NOx more easily and less costly than other methods.
    The flue gas analyzer testo 350 MARITIME can be used for emission measurement on marine diesel engines for measuring the gaseous exhaust gas concentrations of NO, NO2, SO2, CO, CO2-(IR), O2. In order to meet the harsh requirements at sea, the complete flue gas analyzer, including accessories, is housed in a robust protective case with a trolley function – the testo 350 MARITIME flue gas analyzer certainly isn't a landlubber.


    The testo 350 MARITIME flue gas analyzer goes full speed ahead

    As a seaworthy flue gas analyzer, the testo 350 MARITIME can be used for the following on-board verification surveys in accordance with the NOx Technical Code 2008: For the simplified testing and measurement method, for instance if modifications have been made to the engine, such as readjustment
    The testo 350 MARITIME flue gas analyzer is also suitable for checking the NOx limit values stipulated in MARPOL Annex VI. The NOx values are for example tested in official NOx checks. The NOx measurement can also be used to provide proof of NOx reduction, which is required in regional special zones with specific NOx tax requirements (such as Norway).
