Hi Ken; I am not sure what amount is reasonable. The NIST Programmable JJA system is around 400K and has accuracy of near 10 x -12.
A number of the system components are available on the used market, and I cannot speak for NIST, but perhaps they would work with you if you sourced those components used. If that was an option you could bring the cost down substantially. Please feel free to contact me with any other question.

It does not have to be the "programmable" type-- it would be OK if it only produces a single voltage, e.g. 10V or 1V. I was looking at the ETL of Japan-- they have one based on Titanium (or something) that works at slightly higher temperatures, and makes 1V-- so good for liquid helium or a cryo-cooler (but not liquid nitrogen). Where in the world do I *get* one of these things? How much does it cost? Ideas anyone? -Ken _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts volt-nuts Info Page - American Febo Enterprises<https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts> www.febo.com volt-nuts is a low volume, high SNR list for the discussion of precise voltage measurement and related topics.
