Still many ask if the Ex devices shall be Ex certified or not.
All regulations, standards, etc say yes to the topic.
On the other way few believe with an Ex gas sensor aside we are well protected to bring non Ex devices into a hazardous Ex one – which is not correct.
So it means any IOS or Android device to display your documention with possible hazardous environment needs to be Ex certified.
EPDS does it all!
EPDS – explosion protection documentation system – http://epds.hu/
