Digital Melting Point Apparatus-934 & 935

Melting Point Apparatus with 4 digit, 7-Segment LED display is designed for accurate measurement of melting points and for checking the melting range of the solid samples. The apparatus consists of a silicon bath of about 200 ml capacity, covered with teflon cover with 3 holes fitted, with a special type of oil immersion heater having three holes for holding the capillaries, one for boiling point tube and one for the thermometer. The apparatus consists of in-built magnetic stirrer, an electronic controller with indicator for precisely adjusting the rate of heating of silicon oil-bath, an ON/OFF switch, a pilot lamp, with magnifier, a glare free background illuminator, a High/Low range temperature selector switch and digital temperature indicator with PT100 RTD sensor

The 'Start' switch is used to start the measurement of melting point. User can sto the measurement using the 'Stop' switch after the instrument reaches the melting point of the sample. The display will always show the last temperature where 'Stop' switch pressed in the last measurement. Clear switch is used to clear the display to zero.
