Background
Climatic test chamber manufacturers, military testing of electronic components (85:85
ie 85 % rh at 85 °C).

Climatic Chamber Users
Monitoring and control of dew point and/or humidity within a climatic chamber.
The chamber may be used for a variety of product test applications, from aerospace
(military components) to consumer goods testing. Often they test at the extremes of
the temperature and humidity envelope placing high demands on the choice of
reference standard instrument . Low cost humidity probes are not suited to this
application.
