TA Precision RH Perfusion Ampoule

Description

This is used, it powers up.   No other testing has been done.   It is missing the cover on the bottom element.  There are no flow controllers or software included.
From the manufacturer:
The  RH  perfusion  ampoule  perfuses  a
gas of defined relative humidity over a
sample  and  out  through  an  exit  tube.
The relative humidity is controlled using
two mass flow controllers, one of which
passes  gas  directly  to  the  sample  and
the  other  passes  gas  through  two
humidifying  chambers  prior  to  the
sample.  TAM  Assist
ant™  software  con-
trols both the relative humidity and the
total  flow  rate  over  the  sample.  The
software  is  also  used  to  change  the
humidity in a linear ramp or stepwise.
The RH perfusion ampoule is available
in 1, 4 and 20 ml versions. It is possible
to use solvents other than water in the
humidifying  chambers  which  allows  a
gas  of  varying  vapor  pressure  of  a
solvent to be passed over a sample.
