ST-12B Automatic touch screen sugar detector
Automatic touch screen sugar detector temp control 15℃ ～ 35℃ LED
cold light source GB/T 35887
Standard: GB/T 35887 QB/T 5012 QB 5010
The ST-12B fully automatic touchscreen sugar meter is an instrument
used to measure the optical rotation of substances. By determining
the optical rotation of a sample, one can ascertain its
concentration, purity, sugar content, or overall content. It is
widely applied in various industrial sectors such as sugar
manufacturing, petroleum, food, and chemical engineering, as well
as in relevant universities and research institutions. It complies
with GB/T 35887-2018 "Test Methods for White Sugar", QB/T 5012-2016
"Test Methods for Soft White Sugar", and QB 5010-2016 "Test Methods
for Rock Sugar".
Performance characteristics
● LED cold light source instead of traditional sodium lamp and
tungsten halogen lamp;
● It can be used for optical rotation, specific rotation,
concentration, Brix measurement;
● Built-in Peltier temperature control for improved accuracy and
stability.
● LED light sources with a service life of more than 100,000 hours
replace traditional sodium lamps and tungsten halogen lamps, making
up for the shortcomings of short life and easy damage;
● In order to ensure the measurement accuracy of the results, the
instrument temperature control technology adopts built-in Peltier
instead of the traditional flow cell;
● The measuring range has been upgraded to ±89° (optical rotation),
which improves the limitations of the measured sample and improves
the selectability of the measurement sample;
● The control adopts systematic, highly integrated, fully
automated, convenient and easy to operate;
● The multi-level synchronous search function can be upgraded, and
historical data can be retrieved according to test date, sample
number, etc.
