Overview
The WZB 92 Portable digital refractometer is a High Accuracy opticalin strument designed using the principle of refraction, which is small and beautiful, easy to use, and can be easily put in the pocket. LCD large screen LCD digital display, just place a drop of sample solution on the prism, and display the result within 3 seconds to avoid human subjective error interpretation. Suitable for the measurement of liquids such as juice, food and beverages.
Features
1. Compact and portable design, easy to fit in your pocket
2. LCD large screen LCD digital display, clear reading
3. Fast measurement, display results in 3 seconds
4. Automatic temperature compensation function
5. Use more than 10,000 times
6. Automatic shutdown power saving function
7. Temperature display supports Celsius/Fahrenheit conversion
8. Power alarm function
9. High Accuracy measurement, Brix accuracy +/- 0.2%, refractive index accuracy +/- 0.0003
Principle
The instrument is designed based on the principle of refraction, and its concentration is determined by measuring the refractive index of the sample solution. When the ray of light passes through the liquid of different concentrations, it will be refracted. The instrument detects the refraction angle change and converts it into the corresponding concentration value through internal calculation.
Applications
Juices, food, and beverages
Steps
1. Place a drop of sample solution on the prism
2. Wait 3 seconds to read the LCD screen display result
Notice
• Make sure the instrument is fully charged before use
• The sample volume should be one drop during measurement to avoid too much or too little
• Keep the prism clean to avoid contamination affecting Measurement accuracy
• Pay attention to the automatic shutdown function, it will automatically turn off if not used for a long time to save power.
• Charge in time when the battery alarm occurs
