Steve,

I've worked in several low-temp "bio"- type labs, and they all used Fluke 
digital thermometers.  

You can match the thermocouple to the temperature range you need to measure.  
The website can steer you to a dealer or someone for tech questions, but I 
know the J- and K-type thermocouples can read temps down near -200 degrees C.  
That's around the temp of liquid nitrogen (-196) so it should do you well.

Go to Fluke's homepage here.  Then follow the links:
Products -> thermometers -> Fluke 50 Series II Thermometers -> Specifications

Cheers,

Bob
