FlexADOS 914 MED
Multi-channel gas sensor system
Suitability
The multi-channel gas detector system FlexADOS914 MED continuously monitors the ambient air and provides an early warning of harmful, explosive and non-flammable gases and vapours. The evaluation unit has been equipped with a robust cabinet to resist increased mechanical strains as they may occur in the maritime sector. Moreover, the evaluation unit disposes of the class certificate DNV-GL and fulfills the requirements of the Marine Equipment Directive 2014/90/EU (marking: MED wheel mark). Together with the GTR 210 gas transmitter family, FlexADOS 914 MED achieves safety integrity level SIL1 and can be used for primary explosion protection.
