Even the most accurate digital Abbe refractometer requires regular calibration
The digital refractometer is widely used in petroleum, chemistry, pharmacy, sugar manufacturing, food industry and other related universities and scientific research institutions to determine the refractive index nD of transparent and translucent liquids or solids. It can also be used to determine the refractive index nD and Brix value of sucrose solution, Autocorrection the influence of temperature on Brix value of sucrose solution, and display the temperature of sample. It adopts visual aiming, digital display, and can perform temperature correction when measuring the hammer degree. It is also equipped with a standard printing interface, which can directly print data.
1. It has the advantages of an Abbe refractometer.
2. The digital Abbe refractometer adopts new digital and micro processing technologies.
3. The refractive index, temperature, hammer, and temperature corrected hammer are all displayed on the LCD screen.
4. The dial has no scale alignment and reading errors, and the accuracy is very high.
5. Easy to use and operate.
6. It can be equipped with a printer and output measurement results.
7. It can be connected to a computer and can be used to archive and manage measurement data.
The digital refractometer needs to be calibrated regularly, or when there are doubts about the measurement data, it can also be calibrated using distilled water or glass standard blocks for calibration. If there is an error between the measurement data and the standard, a clock screwdriver can be used to correct the small hole in the dispersion correction handwheel, and then the internal screw can be carefully rotated to move the crosshair up and down on the crosshair, and the measurement can be carried out until the measured value meets the requirements. When the sample is a standard block, the measured quantity must match the data calibrated on the standard block.
