The EX detector is ATEX approved and is rated at EEx d IIB + H2 T3 (Tamb

+ H2: Hydrogen gas
T3: External surface temperature will never exceed 200°C.
This approval rating means that the system can be used in an area where an
explosive mixture is likely to occur in normal operation (Zone 1) and where the
gas which is causing the risk is from gas group A, gas group B, or is Hydrogen.
