Hey Bev, good luck.  This is a very loaded question which is highly
dependent upon the "level" of calibration you require.  I am fairly
confident you will not find commercially available services for the whole
system (including software/firmware validation...)  My advise would be to
find a cal lab by asking them if they can calibrate the Keithley of Agilent
electrometers.  This implies that they have (probably Guildline) Teraohm
boxes.  Then convince the lab to come to you. But you'll probably have to
write fairly rigorous procedures (or provide Cookson's) for them to review
before they accept the offer.  Concoat supports their own systems, and they
can supply resistors.  There are a number of resistor sources, but they
don't do me much good unless they themselves are 17025 traceable.  Below are
my favorite High Resistance cal lab contacts.  Guildline is top-shelf, but
unfortunately they will have never heard of a SIRometer.

Subject: [TN] Calibration of SIR equipment


TechNetters,
Back from the dead!

Do any of you know where I can get SIR equipment calibrated?

I have six SIRometers and Cookson/Speciality Coating Systems no longer
support them!  I also have one set of equipment built up from several
pieces of individual Keithley equipment.

Also, does anyone know where I can buy a set of NIST-traceable high
value resistors (E6 - E12)?
Thanks.
