recommends the
following alarm settings for R-123:

These settings are based on the
current acceptable exposure levels
and short-term exposure levels on a
time
weighted average for
refrigerants. SenTech recommends
that under no circumstances should
a refrigerant monitor be set above
the
short-term exposure level.
These are recommended settings

regulations for the appropriate
settings for a given application.

areas have been disabled, press the
“ABORT” key to return to the IR-
