Introduction
Based in Denmark, Danfoss IXA develops emission sensors for the maritime industry. At the heart of its emission sensor, which provides continuous measurements of nitrogen oxides (NOx), sulfur dioxide (SO2) and ammonia (NH3), is a high-sensitivity Ocean Optics spectrometer. This system is ruggedized to withstand operation at sea and designed for simple servicing and minimal maintenance.
Recently, we caught up with Finn Haugaard, Supply Chain Manager for Danfoss IXA, for an update on how the emission monitor is faring and what measurement challenges are ahead for maritime industries.

Ocean Optics (OO): Tell us about your measurement challenge and how Danfoss decided to use spectroscopy for the application.
Finn Haugaard (FH): Danfoss identified a window of opportunity, in terms of providing the maritime industry with a solution for emission measurement that would help ship operators overcome many of the challenges related to existing solutions. The result – the Danfoss Marine Emission Sensor MES 1001 — is easy to put into operation, and hardly requires any effort to maintain. To choose spectroscopy was a rather easy choice, as the technology had already proven to be effective in measuring, for example, sulfur, ammonia and various NOx gases.
