Programmable Melting Point Apparatus
Automatic Programmable Melting Point Apparatus, Order Code : BHI-PTM-4610
designed for accurate determination of melting points automatically
and these melting points are displayed on front panel. It is generally
used to estimate the melting points of organic substances and is
suitable for quality control & research laboratories of chemical,
pharaceutical, food and various other industries.
unit consist of a built-in miniature furnace, a digital temperature
indicating circuitry with necessary controls and an air circulating
arrangement. The furnace is precisely constructed to from a uniform
heating media in which there is an arrangement to hold the capillary
containing the sample. No external heating media like Silicon oil
change in transparency of the sample at the melting point is accurately
sensed by a microprocessor based sensitive electronic circuitry
and the temperature at the melting point is displayed directly on
the digital readout. Being fully automatic instrument, human errors
during the observation of the melting points are totally eliminated.
unit is very simple to operate with minium controls. The expected
melting point of the sample is fed to the microprocessor based by
the keys as 'Set Point' The temperature starts increasing on pressing
the ' Start press switch on the panel and is indicated by a digital
display. The rate of rise in temperature is automatically controlled
in steps and finally adjusts itself at 1°C/Min towards the melting
on reaching the temperature at which the sample melts heating gets
automatically cut off with an audio signal and the air circulating
arrangement starts lowering down the temperature of the system.
The temperature indicating the melting point of the sample remains
displayed on the panel till the 'Clear press switch is operated.
If the actual melting point is beyond te range of adjusted 'Set
Point', the heating stops automatically, as the termperature reaches
10°C, above set temperature of teh program. The range of the
instrument is 40°C to 300°C, Reliability is 0.1°C with
accuracy ± 0.1% The unit works on 230 Volts/50 Hz, A.C. mains
supply. The apparatus is supplied complete with a pack of copinaries
(100 pieces) and on instruction manual.
