Description
Lasany LI-P701 Digital Automatic Polarimeter for Scientific Research & Testing
The Lasany LI-P701 Digital Automatic Polarimeter is a laboratory analytical instrument designed to measure the optical rotation of optically active substances. It supports scientific research, laboratory testing, and quality control applications in pharmaceutical, chemical, food processing, sugar, and beverage industries.
The LI-P701 provides two measurement modes: optical rotation and sugar degree. Its automatic measurement system, LCD display, and servo-controlled operation help laboratories perform routine polarimetric analysis. The instrument also supports average-value calculation, limited result storage, and RS-232 connectivity for supported data transfer.
Key Features
- Automatic measurement: Supports convenient and consistent optical rotation analysis.
- Two measurement modes: Measures optical rotation and sugar degree.
- LED light source: Uses a 589 nm wavelength for polarimetric measurements.
- High-resolution readings: Minimum indication of 0.001° for optical rotation.
- LCD display: Displays measurement results and operating information.
- Average-value calculation: Helps calculate average results from repeated measurements.
- Result storage: Stores up to three measurement results, according to the manufacturer brochure.
- RS-232 interface: Supports data communication with compatible external devices.
- Sample tube compatibility: Supports 100 mm and 200 mm sample tubes.
