WRS-2A/ WRS-2 Micro Processor Melting-point Apparatus
WRS-1B Digital Melting-Point Apparatus
Characteristics
Measurement of melting point is one of the important methods of measurement of purity;
To be used in production of medicines, dye-stuffs, perfumes and other organic crystal substances;
Photoelectric test;
LCD display, entry by digital keyboard and direct display of melting curve;
WRS-2A can measure three samples at the same time and calculate average value of initial and final melting points automatically.
