Overview
BM-2W Abbe refractometer is an instrument used to measure the refractive index nD and average dispersion nF-nC of transparent and translucent liquids or solids, mainly transparent liquids. If the instrument is connected to Thermostat, it can measure the refractive index nD at a temperature of 0 ° C to 70 ° C. The refractive index and average dispersion are one of the important Optical inspection constants of substances, which can be used to understand the Optical Properties, purity, concentration and dispersion of substances. This instrument can measure the percentage of sugar concentration in Sucrose solution (0~ 95%, equivalent to a refractive index of 1.333~ 1.531), and is widely used in the petroleum industry, oil industry, paint industry, food industry, daily chemical industry, sugar industry and geological survey.
Features
1. It can measure the refractive index nD and average dispersion nF - nC of transparent and translucent liquids or solids, mainly for transparent liquids.
2. Thermostat can be used to measure the refractive index nD within 0 ° C to 70 ° C.
3. Can measure the percentage of sugar concentration in Sucrose solution (0~ 95%).
4. Measurement range: nD Measurement range is 1.3000~ 1.7000nD, sugar concentration Measurement range is 0-95%.
5. High Accuracy: nD Measurement accuracy is +/- 0.0003nD, nD resolution is 0.001nD, and the minimum sugar concentration Graduation is 0.5.
6. Optical inspection system is excellent: telescope magnification is 2X, reading mirror magnification is 22X.
7. Durable design: Instrument paints are metal anti-corrosion paint, weight is 5kg.
Principle
The Abbe refractometer is a scientific instrument used to measure the refractive index of a substance, the degree to which the rays of light are bent due to changes in the speed at which light travels through a substance. It measures the refractive index by passing a ray of light through the sample under test and measuring the refractive angle of the ray of light. It works based on the law of refraction and usually includes a light source, a ray of light, a sample chamber, and a measurement device. By measuring incident angles and refractive angles, and using reference materials with known refractive indices, the Abbe refractometer can accurately determine the refractive index of the sample to be tested, which is essential for analyzing the composition, concentration, and Optical inspection properties of the substance.
Applications
Petroleum industry, oil industry, paint industry, food industry, daily chemical industry, sugar industry, geological survey, factories, schools, research units
Steps
1. Prepare the sample to be tested (transparent or translucent liquid or solid).
2. Place the sample in the instrument sample chamber.
3. Pass through the light source rays of light through the sample.
4. measurement ray of light refraction angle.
5. Read the refractive index nD and mean dispersion nF - nC values.
6. To determine the refractive index at a specific temperature, connect the Thermostat and set the temperature (0 ° C to 70 ° C).
7. For Sucrose solution, the sugar concentration percentage can be directly read.
Notice
The instrument is mainly used to determine transparent liquids, translucent liquids or solids to ensure that the sample is suitable for measurement.
• When using Thermostat, ensure that the temperature is set within the range of 0 ° C to 70 ° C.
• Calibrate instruments before measurement, using reference material with known refractive index to ensure accuracy.
• Avoid sample contamination and keep the sample room clean.
• Optical inspection components during operation to avoid scratches or damage.
• The instrument weight is 5kg, and care should be taken to prevent falling when handling.
Store in a drying environment to prevent corrosion of metal parts.
