Sea Sentry

Type approved and MEPC 259(68) accredited Wash Water Monitor for Ship Exhaust Gas Cleaning Systems.

Exhaust emissions from marine diesel engines release gases and particulates that can be detrimental to human health and the environment. To reduce this pollution the IMO has established new regulations through its Marine Environment Protection Committee (MEPC). Ships operating both globally and in Emission Control Areas must now reduce NOX, SOX and particulate emissions. With the global sulphur limit dropping to 0.5% in 2020, the shipping industry must implement strategies to meet this target.
