STNY-105B Touch screen of pesticide specific rotation tester
The STNY-105B pesticide specific optical 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 Optical Rotation Method. It is a specialized
instrument for measuring the specific optical rotation of
pesticides. Using touch screen display and LED cold light source,
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 optical 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 optical rotation at that wavelength and temperature.
Performance characteristics
●Built in Peltier temperature control to improve accuracy and
stability.
●LED light sources with a lifespan of over 100000 hours compensate
for their short lifespan and susceptibility to damage;
●To ensure the measurement accuracy of the results, the instrument
temperature control technology adopts built-in Peltier instead of
traditional flow cells;
●Upgrade the measurement range to ± 89 ° (optical rotation), improve
the limitations of the measured sample, and enhance the selectivity
of the measured sample;
●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 testing dates, sample numbers,
etc.
