-The digital melting-point apparatus is a device used in laboratories to determine the melting point of a substance. It is an upgraded version of the traditional melting-point apparatus, which used a mercury thermometer and a heating source to measure the temperature at which a solid substance changes from a solid to a liquid state.
-The digital melting-point apparatus consists of a heating block, a sample holder, and a temperature sensor. The heating block is equipped with a heating element that provides controlled and precise heating to the sample. The sample holder holds the substance being tested and is inserted into the heating block. The temperature sensor is connected to a digital display, which shows the real-time temperature of the sample.
