How to use a handheld refractometer
Refractometer, also known as refractometer, is an instrument that uses light to test the concentration of liquids. It is used to measure the refractive index, birefringence, and optical properties. The refractive index is one of the important physical constants of matter. The products include handheld refractometers, sugar refractometers, honey refractometers, gem refractometers, digital refractometers, fully automatic refractometers and online refractometers.

Step 1: Open the cover, drop 2-3 drops of distilled water or standard solution on the prism surface, and close the cover.
Step 2: Place the refractometer under the light source and observe through the eyepiece
Step 3: Use distilled water or standard solution as a sample, observe into the eyepiece, and adjust the calibration screw until the boundary line between the blue and white areas completely coincides with the 0 scale line
Step 4: Use the sample solution of the solution to be measured instead of distilled water or calibration solution, then repeat the first step, then the second and third steps, read the scale value of the blue and white dividing line, this scale value is the sample Accurate measurement of solution concentration.
Handheld Refractometer Applications
