What does the MC symbol on the thermometer stand for

This is CMC. You can see that there is a C on the outside of MC, and MC is wrapped in it. This is the mark of measurement certification, which proves that the manufacturer of thermometer has passed the measurement certification. In addition, the measuring instrument produced can ensure the accuracy of measurement value. Without certification, no measuring instrument can be produced
