Is there anything I need to he aware of when using K-type thermocouples?
I got the idea by touching the probe. I can get a reading when measuring temperature for 30 seconds using a DMM. A commercial electronic thermometer needs around minutes for the same result.
This gave me an idea to make a device which will use K-type thermocouple to quickly measure temperature. On the other hand if it was so simple to measure temperature, why don't the commercial thermometers produce their result faster.
I have a feeling that I'm missing something important here.
So my question is: Are there any non-obvious problems I could face when using a K-type thermocouple to measure measure human body temperature?
