Optional Heated Compartment

Two optional internal heated compartments
offer three functionalities:
At first the compartments allow to heat all
physical components at 60° C to avoid
condensation of gases inside the gas path and/
or reduce influence of ambient temperature
fluctuation.
In addition to thermostating the physical com-
ponents this box can be purged and thus allows
to keep out ambient air, interfering measuring
gases at low ranges. The purge medium is
applied to a separate fitting, passes the
electronics, enters the box and exits through
leaks into ambient.

An alternative, gastight compartment allows to
measure corrosive and toxic gases protecting
the electronics and providing operator safety.
With this box the purge medium when applied
to the separate inlet fitting flows through the
electronics, enters the box to flow around the
physical components and than exits through a
purge gas outlet, recommended to be
connected to an exhaust.
