STNY-105B Touch screen of pesticide specific rotation tester
The STNY-105B pesticide specific rotation meter is designed and manufactured in accordance with the NYT 1860.18-2010 Guidelines for Testing the Physical and Chemical Properties of Pesticides Part 18: Specific Rotation Method. It is a specialized instrument for measuring the specific rotation of pesticides. Using touch screen display and LED or other cold light sources, it has a long service life and can detect optical rotation, specific rotation, concentration, etc
Specific optical rotation
At a certain temperature T, the specific rotation of polarized light at a specific wavelength passing through a 1dm light tube and a 1g/L liquid of light substance is called the specific rotation at that wavelength and temperature.
Performance characteristics
● Built in Peltier temperature control to improve accuracy and stability.
● LED light sources with a lifespan exceeding 100000 hours make up for the shortcomings of short lifespan and easy damage;
● To ensure the measurement accuracy of the results, the temperature control technology of the instrument adopts a built-in Parcel patch, replacing the traditional flow cell;
● The measurement range has been upgraded to ± 89 ° (optical rotation), improving the limitations of the measurement sample and enhancing its selectivity;
● The control adopts systematization, high integration, full automation, and is convenient and easy to operate;
● Upgradeable multi-level synchronous retrieval function, which can retrieve historical data based on test date, sample number, etc.
