589nm Automatic Polarimeter
The automatic polarimeter is an instrument used to analyze optically active organic substances, such as sugar solutions, turpentine, and camphor.
By measuring the angle of rotation, one can determine the concentration, content, and purity of the substance under analysis.
Specific applications include:
Testing sugar content and determining starch levels in food products and seasonings.
Clinical medicine: Measuring sugar and protein levels in urine.
Sugar industry: Monitoring the concentration of sugar solutions during the production process.
Pharmaceuticals and fragrances: Measuring the optical rotation of medicinal compounds and essential oils.
Higher education institutions: Use in teaching and laboratory experiments.


No need sample preheat when turning on.
Automatically retest 6 times and calculate the average and root mean square,can measure dark samples.
Available to measure dark-colored sample.
Adopts Peltier principle to control the temperature (only suitable for SGW-2).
Colorful touch screen.
