Digital Melting Point Meter

PTC®'s Digital Melting Point Meters measure the melting point of various substances. It can be used for testing melting points of plastics, waxes, resins, inks, gum, fats, tars, and low melting alloys. A melting point is a temperature at which a substance changes its state from solid to liquid. Under standard atmospheric pressure different pure crystalline solids will each melt at different specific temperatures; thus the melting point is characteristic of a substance and can be used to identify it. The instrument is portable and can be used on any workbench or desk. The unit works on standard 110V AC 50-60 Hz. The warning light next to the on/off switch cautions the user that the heating element is on. The stainless steel platen heats to a 400°F temperature gradient across its length.

An organic compounds melting point is one of several physical properties by which it is identified. A physical property is a property that is intrinsic to a compound when it is pure.

The melting point is the temperature at which a substance changes its state from solid to liquid. Under standard atmospheric pressure different pure crystalline solids will each melt at a different specific temperature; thus the melting point is a characteristic of a substance and can be used to identify it. When heat is applied continuously and in sufficient quantity to such solids, the temperature rises steadily until it reaches the point at which liquefaction occurs.

Here the rise ceases and no further change in temperature is observed until all of the substance has been converted to liquid.The heat being applied to the substance at that temperature is consumed in bringing about the change in state, and none is available to raise the temperature of that part of the substance already liquefied until all of it has changed to the liquid. If heat is still applied when liquefaction is complete the temperature will begin to rise again.
