Maybe you could make a multiplexer.  Here's something I ran across that talks about the problems of switching low voltage signals with nonmagical relays:

Subject: High density thermal diode monitoring

Hello all -

Has anyone implemented a cost effective solution for monitoring large quantities (~96) of thermal diodes for cryogenic temperature monitoring (down to 2K)?  The solution proposed here is either the Lakeshore Model 218 or Model 224, both of which are ~$250/channel ... I was hoping to find something cheaper.

Any proven alternatives?

Thanks -

   Ned


PS: I searched tech-talk and only found solutions for RTDs or thermocouples ...
