Melting Point Apparatus, Usage : Laboratory, Petroleum

We are offering melting point apparatus.
Characteristics:
1) measurement of melting point is one of the important methods of measurement of purity.
2) to be used in production of medicines, dye-stuffs, perfumes and other organic crystal substances.
3) use pid & pwm to control the temperature
4) automatically records the melting curve
5) it can measure three samples at the same time and calculate average value of initial and final melting points automatically.
6) touch screen
7) usb and rs232
