Automatic Polarimeter JH-P400

JH-P400 Digital Automatic Polarimeter is an instrument for measuring the optical rotation of a substance. The concentration, content and purity of substances can be analyzed and determined by the determination of the rotation degree. It is widely used in sugar, pharmaceutical, petroleum, food, chemical and other industrial departments and related universities and scientific research units. Our factory is a professional manufacturer of polarimeters in China.

Digital Automatic Polarimeter Introduction


1: LED cold light source replaces traditional sodium light and tungsten halogen lamps;

2: Can be used to measure optical rotation, specific rotation, concentration, and sugar content;

3: Built-in Peltier temperature control to improve accuracy and stability.

4: Automatic calibration function.

5: Equipped with standard polarimeter;

6: There is user management, which meets the audit trail and complies with the 2015 edition of the Pharmacopoeia.

 Digital Automatic Polarimeter 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.


4.  Fields of use

1. Digital Automatic Polarimeter is widely used in medicine, food, organic chemical industry and other fields.

2. Agriculture: analysis of ingredients such as agricultural antibiotics, agricultural hormones, microbial pesticides and starch content of agricultural products.

3. Medicine: analysis of antibiotics, vitamins, glucose and other drugs, pharmacological study of Chinese herbal medicine.

4. Food: sugar, monosodium glutamate, soy sauce and other production process control and finished product inspection, food sugar content determination.

5. Petroleum: analysis of mineral oil, monitoring of petroleum fermentation process.

6. Fragrance: analysis of essential oils.

7. Health services: analysis of clinical diabetes in hospitals

5.  Product Details

Shanghai Jiahang 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 Shanghai Jiahang automatic polarometer can meet the audit tracking.
