Safely on the right course

The MARSIC200 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 MARSIC200 is type-approved for this application by several classification organizations. The MARSIC200 measures both SOx and CO2 upstream and downstream of the scrubbers, and NOx upstream and downstream of SCR (selective catalytic reduction) plants.

As a leading manufacturer of emissions measurement technology, SICK is offering the MARSIC200 as a modular housing concept. Designed to be used on ships, the measuring device boasts extremely low maintenance costs and modules that are easy to replace.

At a glance
  • Rugged design and high level of measurement accuracy
