  DIGITAL MELTING POINT APPARATUS  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
