ABSTRACT:
The aim of the invention is to reduce the apparatus-related complexity and the mounting effort in a process absorption spectrometer taking in situ measurements. Said aim is achieved by providing the process absorption spectrometer with a unit comprising a source of radiation and at least one additional unit encompassing a detector, both units being embodied as pieces of field equipment and being connected to a field bus.
