Field of application
The MARSIC300 ship emissions measuring device is a customized solution for reliably measuring emissions on ships according to MARPOL Annex VI and IMO MEPC. The MARSIC300 is type-approved for this application by well-known classification organizations. The MARSIC300 measures both SOx and CO2 upstream and downstream of the scrubbers, and NOx upstream and downstream of SCR plants. The measuring device impresses with extremely low maintenance costs and modules that are easy to replace.
Reliable emission monitoring on ships
Accurate DeNOx and DeSOx measurements for ship engines
Cost-efficient process monitoring of the scrubber and catalytic converters
Device properties:
Rugged design and high level of measurement accuracy
Type-approved by well-known classification organizations in accordance with MARPOL Annex VI and IMO MEPC
Measuring ranges adapted to low and high concentrations of SO2 and NOx
Up to 8 measuring components at the same time: SO2, CO2, CO, NO, NO2, NH3, H2O, CH4
