How thermometer is made
NettetWhen making candles, you will need a thermometer at four different points in the process. You will need to measure the heating temperature, melting point temperature, additive temperature, and pouring temperature. It is challenging to make candles without a thermometer, as you will not be sure when to move on to each stage in the process. NettetThe Beurer FT 95 Non-Contact Thermometer failed our accuracy tests and that’s why we’ve made it a Don’t Buy. We tested this thermometer 44 times across 11 temperature points and found that the temperatures given were on average 0.7°C too low. International standards state that thermometers can be out by up to 0.3°C, so we found this …

The expansion and contraction of the air caused the position of the water/air interface to move along the tube. Such a mechanism was later used to show the hotness and coldness of the air with a tube in which the water level is controlled by the expansion and contraction of the gas.
