Zones categories
Zone 0 (gases and vapours)/20 (dust)
Explosive atmosphere is present continuously, for long periods or frequently.
Zone 1/21
Explosive atmosphere is likely to occur under normal operation, occasionally.
Zone 2/22
Explosive atmosphere is unlikely to occur in normal operation and, if it does, will persist for a short period only.

Using of Instrument
PRE5050M-ATEX - Vibrio Ex unit is certified for using in explosive risk areas zones 1 and 2 with all gases group.


It means:
