2.8.  Data security information 
Honeywell gas analyse devices are used in modern infrastructures and network control systems 
with  the  aim  of  transferring  process  information  such  as  meter  readings,  measurements  and 
messages to a central billing or control point. A connection of this type constitutes a significant 
security risk which must be given careful consideration when designing the network.
