Specifications
Model MICROCAL 20 DPC iS marked with label "Ex" has been built in accordance with European Norm
II 2 (1) G EEx-ia IIC T4
and may be used in IEC defined zones 0,1 and 2.
The Intrinsically Safe (IS) is a security standard applied into potential explosive environmental. The "Intrinsically Safe" certified instruments are been designed and made in order to do
NOT release thermal and electric energy able to induce the ignition of flammable materials (gas) even in case of malfunction or connection errors.
The MICROCAL 20 DPC iS is a ATEX directive compliant calibrator and it is certified as II 1G Eex IA IIC T4.
The explanation code is as follows:
II
Apparatus Grouping: all the applications except mines with Grisou.
1G
Category: permanent presence of explosive gas (zone 0) except zones with explosion danger due to powders
Eex
Explosion protection by the European regulation
