The MARSIC300 ship emissions measuring device from SICK is an innovative 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 (selective catalytic reduction) plants.
