FlexADOS 914
Multi-channel gas sensor system
Suitability
The multi-channel gas detector system FlexADOS 914 continuously monitors the ambient air and provides an early warning of harmful, explosive and non-flammable gases and vapours. Together with the GTR 210 gas transmitter family, FlexADOS 914 fulfils EN 50271:2011, achieves safety integrity level SIL1 and can be used for primary explosion protection.
