ST-12B Automatic Touch Screen Sugar Detector Upgrade Your Testing
with LED Light Source and Built-in Peltier Technology
ST-12B The automatic touch screen sugar detector is an instrument
for measuring the optical rotation of substances. The
concentration, purity, Brix or content of the sample can be
determined by determining the optical rotation of the sample.
Widely used in sugar, pharmaceutical, drug testing, food, spices,
monosodium glutamate and chemical, petroleum and other industrial
production, scientific research, teaching departments, for
laboratory analysis or process quality control, through the
determination of screwing photometry, Brix, can analyze and
determine the concentration, content and purity of substances,
etc., widely used in sugar, pharmaceutical, petroleum, food,
chemical and other industrial departments and related colleges and
research units.
Performance characteristics
lLED cold light source instead of traditional sodium lamp and
tungsten halogen lamp;
lIt can be used for optical rotation, specific rotation,
concentration, Brix measurement;
lBuilt-in Peltier temperature control for improved accuracy and
stability.
lLED 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;
lIn 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;
lThe control adopts systematic, highly integrated, fully automated,
convenient and easy to operate;
lThe multi-level synchronous search function can be upgraded, and
historical data can be retrieved according to test date, sample
number, etc.
