recommended that the operator review the
Gas Code screens for a complete list of
gasses a given monitor is capable of

Unless
specified
otherwise,
SenTech
Corporation recommends the following
alarm settings for R-123:
Low = 25 ppm

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 only. Refer to local
codes and regulations for the appropriate
settings for a given application.
