Why Does My Thermocouple Show Incorrect Temperatures?

[Kaly]

Hello,

Has anybody used it before? I am having trouble regarding readings it is giving me.. It seems to raise the temp when T type thermocouples are dipped in ice and lower the temp when dipped in hot water.. numbers don't make sense to me. Please help

Can you post a lot more info on your DAQ setup? What instrument are you using to measure the temperature? How are you connecting to it (Ethernet, USB, wireless, etc.)? What type of thermocouple are you using, and are you sure your temperature measuring device matches that thermocouple type?
