ST-12B Automatic touch screen sugar detector
ST-12B automatic touch screen sugar detector is an instrument for
measuring the optical rotation of substances. The concentration,
purity, sugar content or content of the sample can be determined by
measuring the optical rotation of the sample. It is widely used in
sugar making, pharmaceutical, petroleum, food, chemical and other
industrial sectors, as well as relevant colleges and universities
and scientific research institutions, and conforms to GB/T
35887-2018 test method for white granulated sugar, QB/T 5012-2016
test method for white sugar and QB5010-2016 test method for rock
sugar.
Performance characteristics
● LED cold light source replaces traditional sodium light lamp and
tungsten halogen lamp;
● It can be used for the measurement of optical rotation, specific
rotation, concentration and sugar content;
● Built in Peltier temperature control to improve accuracy and
stability.
● The LED light source with a service life of more than 100000
hours replaces the traditional sodium light lamp and halogen
tungsten lamp, making up for the shortcomings of short service life
and easy damage;
● In order to ensure the measurement accuracy of the results, the
instrument temperature control technology adopts the built-in
Peltier instead of the traditional circulation tank;
● The measurement range is upgraded to ± 89° (optical rotation),
which improves the limitations of the measured samples and improves
the selectivity of the measured samples;
● The control is systematic, highly integrated, fully automated and
easy to operate;
● Multi level synchronous retrieval function can be upgraded, and
historical data can be retrieved according to test date, sample
number, etc.
