2-1 OVERVIEW
a. Limitations
Ambient Temperature:-30 ° to 50° Celsius
(-4 ° to 122° F)
Relative Humidity:5% to 99%
b. Mounting Options
Although the MicroCEM is enclosed in an
environmentally sealed enclosure, it
should be protected from direct sunlight.
In areas subjected to harsh winter cli-
mates, protection should be provided from
sun, rain and snow. A corrugated awning
or other suitable means can be provided
to meet these conditions.
2-2 LOCATION
The MicroCEM is designed to be installed in
an outdoor environmental location. It is rec-
ommended that the analyzer be located out of
direct sunlight and direct rain/snow to the ex-
tent possible.
The MicroCEM analysis enclosure should be
installed as near as possible to the
probe/sample handling enclosure, in order to
avoid low response time caused by long sam-
ple gas lines.
