All thermometers are only as good as their calibration. There is nothing intrinsically better about mercury over alcohol, or electronic.
Please share your source that electric is unusable, when all first world hospitals use electronic exclusively. I have half a dozen aliexpress thermometers for home automation, they all track the temperature identically, they just need to be calibrated first, and once.
While your at it, what is wrong with alcohol based thermometers? They are built the same way, how could they be worse?











I’ve done a little, it could definitely fall into type 2 depending on the person.
