Model : CDMP-300

Melting Point Apparatus measures the melting point of a substance i.e. the temperature at which the state of the substance changes from solid to liquid. The actual melting point is an indication of the purity of a substance and hence an ideal tool for the quality control of medicines, perfumes, dyestuff and other organic crystalline substances.

  • Photo Electric detection.
  • Large Backlite LCD display.
  • RS-232 Interface.
  • Measurement of 3 samples simultaneously.
  • Display of initial and final melting points.
  • Calculation of average value of initial and final melting points.
  • Platinum resistor sensor for the precise temperature measurement.
  • Capillary sample tube as stipulated by pharmacopoeia
