3. Product feature
1: The LED light source with a service life of more than 100,000 hours replaces the traditional sodium lamp and tungsten halogen lamp, which makes up for the short-lived and easy-to-damage shortcomings;
2: In order to ensure the measurement accuracy of the results, the temperature control technology of the instrument adopts built-in Peltier instead of the traditional flow cell;
3: The measurement range is upgraded to ±89° (optical rotation), which improves the limitation of the measurement sample and improves the selectability of the measurement sample;
4: The control adopts systematic, highly integrated, fully automated, convenient and easy-to-operate.

5. Product details
Yuke Digital Automatic Polarimeteris an instrument for measuring the rotation of substances. The concentration, content and purity of the substance can be determined by spectrophotometry. Shanghai Jiahang Automatic Polarimeter has built-in Peltier precise temperature control system, which can meet users' requirements for testing at constant temperature. The built-in automatic calibration program is optional, and the standard automatic calibration tool can be automatically calibrated from -45 degrees to +45 degrees, which fully meets the user's demand for controllable measurement accuracy in daily operation. The multi-level authority management of Yuke automatic polarometer can meet the audit tracking.
