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.
