*) Extended range: The sensor extended temperature range is greater than the maximum specified in
EN 60079-29-1. It is therefore strongly recommended that if used above +55 °C or below -25 °C the
sensor is calibrated at the operating temperature.
**) The storage temperature range is also valid for spare parts and accessories
