Description

Description

Automatic polarimeter can automatically measure the optical rotation of optically active substances. This measurement can be used to analyze parameters such as concentration, content, purity, sugar content, and specific rotation. These instruments are widely used in sugar refining, pharmaceuticals, food, quality inspection, chemical industry, agriculture, light industry, petroleum, and other industrial sectors, as well as relevant universities and research institutions.

Features

Multiple Test Modes, Automatic Repeat Measurement

POL-2P/1P/3 offers four measurement modes: optical rotation, specific rotation, concentration, and international sugar scale, meeting diverse testing needs. The automatic repeat measurement function allows for up to six consecutive tests and automatically calculates the average, effectively improving data reliability. The POL-2P/1P also calculates root mean square (RMS) values, enabling accurate measurement of dark samples.

Long-Lasting Light Source

The LED light source has a lifespan of over 100,000 hours, effectively avoiding the hassle of frequent replacement required with traditional sodium lamps.

Intelligent Temperature Control, Accurate and Reliable Results

POL-2P feature built-in high-precision Peltier temperature control devices with heating and cooling functions. They support the use of temperature-controlled sample cells for polarimetry measurements, ensuring samples are tested at the required temperature and guaranteeing data accuracy.
