I bought a new milk thermometer and its different to my old one by several degrees. The milk frothing seemed different so I put three thermometers into a mug of warm water and left them for 15 minutes or so. The newest one read 39C, the older milk thermomter read 31C and my fish tank thermometer read 30C.
How many people have had poorly calibrated thermometers? Are the digital ones better calibrated?
