Overview
SUOGUANG WYA-2D digital Abbe refractometer is an opticalin strument used for the measurement of liquid refractive index, which is widely used in chemistry, biochemistry, food science and other fields.
Features
1.6-Bit OLED LCD digital display function, high linear accuracy, while displaying refractive index, sugar value, temperature
2. Built-in lithium battery, continuous working time of more than 72 hours
3. Automatic and manual sleep function, normal use for 10 days without charging
4. Type_C USB interface, data transmission can be charged at the same time
5. USB data transmission with time stamp, can store 100 sets of data when working offline
6. Small size, easy to carry, can be connected to a constant temperature water bath
Principle
The Abbe refractometer is based on the refraction phenomenon of ray of light in different media. When the ray of light is deflected when it is injected into the liquid from the air, the instrument uses a prism to hold the liquid sample to be tested, emits monochromatic light after passing through the sample to observe the offset angle of the refracted ray of light, and infer the refractive index of the sample to be tested by comparing it with the standard sample, so as to know its composition or concentration.
Applications
Chemistry, Biochemistry, Food Science
Steps
1. Prepare the liquid sample to be tested
2. Place the sample in the instrument prism
3. Start the instrument for measurement
4. Read the refractive index, sugar value and temperature data on the display screen
5. Data can be transferred or stored via USB interface
Notice
• Make sure the instrument is fully charged before use
• Keep the sample clean and free of impurities during measurement
Avoid use in extreme temperature environments
• Regularly calibrate instruments to ensure Measurement accuracy
• When not in use for a long time, it is recommended to charge and save it.
