Monocular Abbe refractometer 2WAJ
Abbe refractometer 2WAJ 1. Instrument Application Abbe refractometer is an instrument that can measure the refractive index nD and average dispersion
Product details
Abbe refractometer 2WAJ

1、 Instrument usage
The Abbe refractometer is an instrument that can measure the refractive index nD and average dispersion nF nC of transparent, semi transparent liquids or solids (with a focus on measuring transparent liquids). If a thermostat is connected to the instrument, the refractive index nD can be measured at temperatures between 0 ℃ and 70 ℃. Refractive index and average dispersion are important optical constants of a substance, which can be used to understand its optical properties, purity, and dispersion size.
This instrument can measure the mass fraction (Brix) of sucrose solution (0-95%, equivalent to a refractive index of 1.333-1.531). Therefore, the instrument has a wide range of applications and is one of the indispensable commonly used equipment in factories, schools, and research institutions related to the petroleum industry, oil and fat industry, pharmaceutical industry, paint industry, daily chemical industry, sugar industry, and geological exploration.

2、 Characteristics:
Adopting visual aiming and optical dial reading, it is easy to operate and convenient to use. Measure the refractive index n of liquid or solid and the mass fraction of dry solids in sugar water solution, i.e. BriX. Can be used for testing and analysis in sugar, pharmaceutical, beverage, petroleum, food, chemical industry production, scientific research and teaching departments.

3、 Main technical parameters and specifications
1. Refractive index measurement range (nD): 1.300-1.700
2. Accuracy (nD): ± 0.0002
3. Sucrose solution mass fraction (Brix) reading range: 0~95%
4. Instrument dimensions: 100 × 200 × 240mm
5. Instrument weight: 2.6kg

4、 Instrument calibration
The instrument can be calibrated regularly or when there are doubts about the measurement data. Calibration using distilled water or glass standard blocks. If there is an error between the measured data and the standard, a clock screwdriver can be used to pass through the small hole in the dispersion correction handwheel, carefully rotate the screw inside, move the cross line on the dividing plate up and down, and then measure again until the measured value meets the requirements. When the sample is a standard block, the measurement should conform to the data calibrated on the standard block.
If the sample is distilled water, the measured values should comply with the following table:
