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
l LED cold light source instead of traditional sodium lamp and tungsten halogen lamp;
l It can be used for optical rotation, specific rotation, concentration, Brix measurement;
l Built-in Peltier temperature control for improved accuracy and stability.
l 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;
l 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;
l The control adopts systematic, highly integrated, fully automated, convenient and easy to operate;
l The multi-level synchronous search function can be upgraded, and historical data can be retrieved according to test date, sample number, etc.
