Thermocouple good at room temp is good always?

Hi,
If you are about to do thermal tests with thermocouples...then to see if they are ok...can you say they are ok, if when in the thermocouple reader, with the end junction bits loose on the lab table, then if they read room temp properly , then those thermocouples are OK? (at all other temps too). We only need accuracy to within about 4 to 5 degrees.

The thermocouple works well at room temperature. A thermocouple's quality depends on its design, material, environmental effect, and its accuracy, which is changeable. I like this thread; it is interesting for me.
