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.
