Logo of ATEX





European ATEX directive 1999/92/EC has been in force since 2006 and requires implementation of a risk analysis procedure to ensure human safety.

STid supports industrial users, integrators and installers in implementing contactless access control and identification solutions in explosive atmospheres.

We offer a full range of certified RFID readers that meet the two watchwords of the industry - safety and reliability. Our solutions comply with all industry-related international standards: ATEX (EN60079) & IECEx certifications and European Directives (99/92/EC and 94/9/EC).
