Operating steps:

1. Open the shading plate counterclockwise.

2. Use the pure water to clean the detection slot with soft cloth, then remove the residual water.

3. Add 3-5 drops of liquid test sample to the detection slot.

4. Closed the shading plate clockwise.

5. Press the “On|Off/Read”shortly, or touch the “touch instruction point”. The screen shows the value of BRIX.  Press the “Zero” shortly, The screen will show the value of Refractive index.

Zero point calibration

1, Use the pure water to clean the detection slot with soft cloth repeatedly.

2, Add 3-5 drops of pure water to the detection slot.

3, Press and hold the“Zero”, until the screen shows “ zeroing”, release the button and start.

4, When the Screen shows “Zero Success”, mean the Zero point calibration is finished.

  When the screen shows “Zero Failure”, mean the Zero point calibration is failed.

5, Press the “On|Off/Read” When the value is “0.0%”, mean the Zero point calibration is succeed.

What is a Refractometer?

A refractometer is a simple instrument used for measuring concentrations of aqueous solutions. It requires only a few drops of liquid, and is used throughout the food, agricultural, chemical, and manufacturing industries.

How a Refractometer Works

When light enters a liquid it changes direction; this is called refraction. Refractometers measure the degree to which the light changes direction, called the angle of refraction. A refractometer takes the refraction angles and correlates them to refractive index (nD) values that have been established. Using these values, you can determine the concentrations of solutions. For example, solutions have different refractive indexes depending on their concentration in water.

The prism in the refractometer has a greater refractive index than the solution. Measurements are read at the point where the prism and solution meet. With a low concentration solution, the refractive index of the prism is much greater than that of the sample, creating a large refraction angle and a low reading ("A" on diagram). The reverse would happen with a high concentration solution ("B" on diagram).
