YJ-7100G Automatic Polarimeter

I. Main Applications:

The polarimeter is an instrument used to measure the optical rotation of substances. By determining the optical rotation of a sample, the concentration, purity, sugar content, or composition of the sample can be ascertained. It is widely used in sugar production, pharmaceuticals, drug testing, food, flavorings, monosodium glutamate, as well as in industrial production, scientific research, and educational sectors such as chemical and petroleum industries for analytical testing or process quality control.

II. Main Features:

Utilizes photoelectric detection and automatic servo mechanism control, with digital display for readings, capable of measuring dark-colored samples; also capable of measuring sugar content, and equipped with an RS232 interface for data transmission to a PC.

III. Main Technical Parameters:

1. Measurement Range: -45° to +45°; -120°Z to +120°Z

2. Minimum Readable Value: 0.001°; 0.01°Z

3. Accuracy: ±(0.01° + measured value × 0.05%); ±(0.03° + measured value × 0.05%)Z

4. Repeatability (Maximum Deviation): ≤0.002°; ±0.006°Z

5. Minimum Sample Transmittance: 1%

6. Dimensions: 600mm × 320mm × 220mm
