Intrinsic Safety

Intrinsic Safety is a method used to limit the amount of energy, heat or ignition sources entering a hazardous zone containing or potentially containing an explosive atmosphere.


ATEX is the European Directive for governing health and safety in explosive environments.

ATEX zone rating for LEO1 Ei digital manometer

LEO1 ATEX coding

Is the LEO1 Ei digital manometer safe to use in a zone 1 ATEX area? Yes, the LEO1 is ATEX approved to II 1 G EEx ia IIC T6 or T5, which is actually zone 0, so higher rated than zone 1.
