Hot surface
Note on calibration
The operator must check the label, which is important for the use in potentially explosive atmospheres, at regular
intervals to ensure that it remains legible.
The outer packaging is labelled with the type designation, order number, item number, measuring range and
manufacturer's data.
2.6 Safety devices
The window is made of laminated safety glass, no other material options are permitted here.

2014/34/EU ATEX & Regulation SI 2016, No. 1107
3.1 Range of use:
Potentially explosive atmospheres Zone 1 and 2, as well as 21 and 22, hazard due to gases and dry dusts.
The permissible environment has the usual oxygen content (21%), ambient pressure 80 kPa (0.8 bar) to 110 kPa (1.1
bar).
The requirements of the applicable standards EN ISO 80079-36, EN ISO 80079-37, EN 60079-0 were considered by
