How do you know if a thermometer is accurate?
What do you use for a base line?

Boiling water, but don't expect to have it read a full 212/100 unless the probe is in contact with the pan. In boiling water my fluke reads 211, the other thermocouple usually reads around 211.5.
Ice and water slush, this will read 32/0.
Choose the calibration method for where and what the thermometer will be used to measure.
