Beni,
I have interesting news for you all at Jefferson Labs. A
schedule change has allowed Servomex to be able to come to VA now this week
with a live Gas Analyzer "Demo Van". This is an actual Servomex bannered
drivable van that has "Live" Analyzers inside running for you to actually
see them and put your hands on them. We'd like to come anytime on Thursday
that you are available. We could either drive it in to your lab areas inside
the gates near the Halls for Engineers and Scientists to come out and take a
look at all the different Technologies. OR, we could park it near the main
bldg/Cafeteria where we "normally" meet and allow you and any other Analyzer
interested individuals to come out, jump inside the van, put your hands on
5-6 different Technology Analyzers, ask the Servomex Technical Specialist
with the van any questions and go from there for any future needs. As a
backup if Thur was 100% unavailable for your schedules, we could be there
Wed late afternoon as he travels east from Richmond area. Please let me know
if Thursday works for you and what time is best (or if we have to meet late
Wed afternoon). I await your availability date and time.....
Sincerely,
Mark Montague

Hi Mark,
attached are the two updated drawings of the gas system.
I added only one reference gas for the o2 sensor at the exhaust of the
chamber because that is a mixture of Ar/CO2. Do we need a different
reference gas for different Ar/CO2 mixtures?
cheers,
Beni
