In situ oxygen measurement
Fields of application
This analysis system is designed for demanding applications in potentially explosive atmospheres, such as refinery furnaces, petrochemical furnaces and large industrial boilers.
Features
The Atex in-situ oxygen analyser is designed for combustion control in hazardous areas (refining and petrochemical furnaces, industrial boilers).
Measuring the oxygen concentration in the effluent enables the air/fuel ratio characterizing combustion to be monitored.
This is essential for controlling efficiency and ensuring process safety. This analysis system is designed for demanding applications in potentially explosive atmospheres:
The ZFKX detector is ATEX and IECEx certified and can be used in environments classified as Zone 1 IIB+H2 T3 Gb.
