Description: Mercury Glass Thermometer Large Screen Clinical Temperature Household Health Monitors Thermometers Material:The outer box is plastic, the thermometer is glass Color, Size and Styles: show the pictures Quantity: 1 pc Measuring range: 35-4295-107.6 Why is the "35" scale of some mercury thermometers a little higher from the bottom, and some mercury thermometers "35" the scale is lower from the bottom? Will this be inaccurate? This is because the thickness of the bottom mercury jug glass is different when the thermometer is blown, that is, if the wall is thick, the volume is slightly smaller, the mercury surface is higher, and the starting point of the scale is higher, and the volume if the wall is thinner Slightly larger, the mercury level is lower, and the starting point of the scale is also lower, but the measured body temperature should be the same.
