YJ-7100D Automatic Polarimeter
I. Main Applications:
A polarimeter is an instrument used to measure the optical rotation of substances. By measuring the optical rotation of a sample, the concentration, purity, sugar content or content of the sample can be determined. It is widely used in industrial production, scientific research and teaching departments such as sugar manufacturing, pharmaceuticals, drug testing, food, spices, monosodium glutamate, chemical industry, petroleum, etc., for laboratory analysis or process quality control.
II. Main Features:
Adopting photoelectric detection and automatic servo mechanism control, with backlit LCD display, the test data is clear and intuitive. It can save three re-measurement results and calculate the average value.
III. Main Technical Parameters:
1. Light source: LED lamp + filter, wavelength 589.44 nm
2. Minimum transmittance of measurable sample: 10%
3. Measurement range: ±45° (optical rotation)
4. Minimum reading: 0.002° (optical rotation)
5. Accuracy: ±(0.01° + measured value × 0.05%)° (optical rotation)
6. Repeatability (standard deviation α): ≤0.01° (optical rotation) when the sample transmittance is greater than 10%
7. Sample tubes: 100mm, 200mm
8. RS232 interface
10. External dimensions: 600mm×320mm×200mm
11. Net weight: 30kg
12. The photomultiplier tube adopts an imported photomultiplier tube from Hamamatsu Photonics, Japan
13. The polarizer adopts an imported polarizer from Olympus, Japan
