X-Message-Number: 2054 Subject: CRYONICS Thermocouples Date: Sat, 03 Apr 93 11:48:11 EST From: Fisher Scientific sells thermocouple thermometers that can go down to -250 degrees C. They also high temperature ones that can go down to -190 degrees C. (To be fair, the phrase "high temperature" refers to the maximum temperature, not the minimum.) Does it follow that thermocouple cooling can cool things to -250 degrees C? Tim Freeman Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=2054
