Hi Ralph,

My past experience with older 1A and 1B MIRAN units is that they are more
trouble than they are worth in an emergency response setting (and at most
other times as well), especially in labs where you generally have some idea
of what you are dealing with.  When given a choice I have set things up with
multi-gas meters and a variety of sensors (e.g. Draeger mini-warn).  With
that said, I recently investigated the use of the SapphIRe unit for a
project and was re-assured that it was more reliable, easier to use, etc.
Sorry no personal experience though.  Might be a good question for the AIHA
list

Subject: [DCHAS-L] Thermo MIRAN SapphIRe
Importance: Low

I wonder if anyone on the list has experience with the
MIRAN
SapphIRe unit? We're considering it for use as a qualitative and
quantitative instrument during laboratory emergency response where
there may be a variety of chemicals involved. We're concerned that
PID results tend to be too confusing to interpret in these
situations, where a variety of chemicals are involved at low levels...
