YJ-7100K Fully Automatic Constant Temperature Polarimeter

A polarimeter is an instrument used to measure the optical rotation of substances. Through the measurement of optical rotation, the concentration, content, purity and other properties of substances can be analyzed and determined. It is widely used in industrial sectors such as sugar processing, pharmaceuticals, petroleum, food, and chemical industry, as well as in relevant institutions of higher learning and scientific research units. It uses a light-emitting diode (LED) as the light source, avoiding the trouble of frequently replacing sodium lamps. The built-in temperature control device of the instrument has both heating and cooling functions. If a temperature-controlled sample tube is used, temperature-controlled measurement of the sample's optical rotation can be performed. The large-screen liquid crystal display on the instrument provides a human-computer interaction menu operation mode, which is simple, intuitive, stable and reliable.

The main technical parameters are as follows:

1. Measurement modes: Optical rotation, specific rotation, concentration, sugar degree

2. Light source: Light-emitting diode (red light source)

3. Working wavelength: 589.3nm (sodium D spectrum)

4. Measurement range: ±89° (optical rotation)

5. Minimum reading: 0.001° (optical rotation)

6. Indication error: ±0.01° (when -15° ≤ optical rotation ≤ +15°)

±0.02° (when optical rotation < -15° or optical rotation > +15°)

7. Repeatability (standard deviation s): 0.006° (optical rotation)

8. Temperature control range: 15℃-30℃

9. Temperature control accuracy: ±0.5℃

10. Display mode: Extra-large screen liquid crystal display
