3.1. Use
Do not use the testo 350 MARITIME for continuous flue gas measurements, i.e. the sensors must be regularly rinsed with fresh air. Recommended measurement periods and rinse phases, see Recommendation for emissions measurements over an extended period of time, page 89.The testo 350 MARITIME is a portable
flue gas analyser, which can be used as a system component within a complete monitoring system to measure flue gas emissions from marine diesel engines in accordance with MARPOL 73/78 Annex VI and NOx Technical Code 2008 (MEPC.177(58)). In order to fully comply with the on-board detection procedure of the “Direct Measurement and Monitoring Method” MARPOL 73/78 Annex VI and NOx Technical Code 2008 (MEPC.177(58)), additional parameters must be recorded.
The testo 350 MARITIME has been designed for the following applications:
• The testo 350 MARITIME can be used as a system component to measure the gaseous flue gas concentrations of O
2
, CO,
CO
2
, NOx and SO2for the following procedures:
• for periodical examinations and for intermediary
examinations for direct measurement and monitoring on board
• as a component for a simplified test and measuring method
(HC must be measured separately
• testing the NOx limits specified in MARPOL Annex VI for official NOx monitoring measurements on board.
• NOx measurement as proof in regional special zones, e.g. as proof of NOx reduction for NOx tax in Norway
The flue gas analyser testo 350 MARITIME is certified by DNV GL for measuring gaseous flue gas components as a system component (e.g. for the “direct measurement and monitoring” on board procedure, and for simplified measurement procedures).
Other system components required in accordance with NOx Technical Code for the “direct measurement and monitoring” on board procedure are not included in this certification!
