FlexADOS 914 CP
Measuring, control and warning unit for sensors
Suitability
The FlexADOS 914 CP is a measuring, control and warning unit for gas sensors. It continuously monitors the ambient air and provides an early warning of harmful, explosive and non-flammable gases and vapours. Together with the 592 TOX gas transmitters, FlexADOS 914 CP fulfils VDI guideline 2053 from December 2014 and also EN 50271.
