UV-DOAS sulphur monitoring for MARPOL Annex VI compliance and scrubber control.
M800C is the marine version of the System 400 platform: all components are modified for shipboard installation and approved by the major classification societies.
SO₂ and CO₂ concentrations, and the SO₂/CO₂ ratio used to demonstrate compliance with the sulphur limit. The same system can monitor scrubber efficiency.
Cross-stack, fast-loop or hot wet extractive arrangement, one measurement path as standard and up to nine paths with an optical multiplexer. Data acquisition through WT256 for local and remote access.
