It is always interesting to have a TS diagram in your trail when you want to explain something to somebody. It can help a lot.
I have some A3 format TS diagrams in my trail. They are readable but they are coming from copies of copies of copies, etc. If you want a really nice, big-format diagram, maybe it is best to
ask the following places directly:
– National Bureau of Standards, Cryogenic Engineering Laboratory,
Boulder, Colorado
or
– International Institute of Refrigeration
or
– the Kamerlingh Onnes Laboratory, Leiden
It works in Excel and includes a property calculator for a number of gases including helium, nitrogen, oxygen, argon, and water. It will also handle fluid mixtures albeit with some limitations.
Typically, for single components, it will go down to the freezing temperature of the fluid and in the case of helium down to the Lambda temperature of 2.17 K. For helium below the Lambda temperature I use my own data collected from various sources.

August 23, 2012Of course I’ve looked at Goran’s page first, but the diagram there is not as detailed as I wanted – nor is it really printable.
I’m looking for a good old-fashioned black-and-white, high-resolution diagram, the one that everyone has on their wall.

August 23, 2012Indeed.
And thanks again for the pointers, Luc.
I haven’t found anything directly downloadable on any site, though.
– I have mailed NIST / NBS
– IIR doesn’t seem to have anything
– neither does the Leiden Lab
Any other ideas ?
