DIGITAL
POLARIMETER
Polarimeter is an instrument used for determining
optical rotation of substances. It is also used for
measuring specific rotation, concentration &
international sugar scale of optically active
substances. Polarimeter is ideal for pharmaceutical,
food and beverages, sugar, cosmetics, oil refinery,
chemical industries & also scientific research studies.
CONTECH Digital Polarimeter is a fully automatic
instrument and eliminates the need for manual
adjustments thus offering a high degree of measurement
precision.
The polarized light after passing through the sample
falling on the analyzer deviates from the optical zero
position to the extent of optical rotation of the sample
and the photomultiplier detector will produce an
electrical signal with the frequency corresponding to
the optical rotation of the sample. This signal after
passing through the selective frequency circuit and
power amplifier drives the servo-motor & in turn the
analyzer until the optical zero position is regained.
The analyzer rotation is measured by an encoder and is
displayed on the digital readout as the optical rotation
of the sample.
