These features help keep teams connected and protected when working alone in hazardous or remote environments.
Zone 1/21 devices are certified for areas where an explosive gas or dust atmosphere is likely to occur during normal operation, which is the more demanding classification. Zone 2/22 devices are certified for areas where such an atmosphere is only likely to occur occasionally or for short periods. Selecting the correct range depends on the area classification of the site, so it is worth confirming the zone requirement before ordering.
