Product Description
NADE WRS2A laboratory Microprocessor melting point instrument/apparatus Room temp -300C
In according with the definition of physical chemistry, the melting point of substance means the temperature at which the substance changes from solid state to liquid state.In the field of organic chemistry, the measurement of melting point is a basic means of organic chemistry, the measurement of melting point is a basic means of
recognizing the nature of substance, and is also one of the important place in the chemical industry and medicine researches.Also, the melting-point meter is a kind ofnecessary instrument in the production of medicines, perfumes, dyestuff and other organic crystal substances.
Microcomputer melting point meter uses the technology of photoelectric detection and temperature display by liquid crystal. Type WRS-2A could measure three sample at the same time. It has the functions of automatic displaying of initial and final melting points, automatic recording of the melting curves and calculating average value. The temperature system uses the linearly corrected platinum resistor asthe detecting element, and additionally, it uses the integrated circuits to realize the speedy setting of eight-step linearly heating rate for being selected .Since the initial and final melting-point readings can be stored up automatically, there is no
need for this function to be monitored manually.
