Brix Refractometer with ATC, Dual Scale Specific Gravity & Brix Homebrew Kit

Product name: Handheld wine concentration meter 25-40%

1. Main technical parameters:
   Measuring range and minimum scale: Sugar content: 0-40% Minimum scale: 0.2%
   Alcohol content: 0-25%
   It has a temperature compensation function to overcome data deviation caused by temperature changes and make the data more accurate.
   The eyepieces have been upgraded. The lens glass is heavy crown optical glass, not ordinary glass, which has higher clarity and reduces the observer’s fatigue.

2. How to use:
   1) Align the refractive prism in the direction of light and adjust the eyepiece diopter ring until the reticle is clear;
   2) Adjust the standard: Before measurement, first make the standard solution (purified water), instrument and liquid to be measured based on the same temperature. Open the cover, then put 1 to 2 drops of standard liquid on the refractive prism, and gently press the cover with your hand to draw a dividing line between light and dark. Rotate the calibration bolt so that the light-dark dividing line in the eyepiece field of view coincides with the reference line (0%);
   Note: This optical instrument has been adjusted before leaving the factory and can be used directly.
   3) Open the cover, wipe the surface of the prism with a soft flannel, put 1~2 drops of the solution to be measured on the refractive prism, cover the cover and press gently, read the relative scale of the dividing line between light and dark, which is the measured value. The concentration value and density value of the liquid.
   4) After the measurement is completed, directly wipe off the attachments on the prism surface and cover with a damp flannel, and store them properly after drying.
   Correction
   The instrument needs to be calibrated to zero before measurement. Take a few drops of distilled water, place it on the detection prism, and turn the zero adjustment screw to adjust the dividing line to the 0% position of the scale. Then wipe the detection prism and perform detection. Some models of instruments require standard solutions instead of distilled water during calibration.
   Precautions
   This instrument is a precision optical instrument. Please pay attention to the following matters during use and maintenance:

3. You must be careful during use and use it strictly according to the instructions. Do not loosen the connecting parts of the instrument at will. Do not drop or collide. Violent vibration is strictly prohibited.
4. After use, it is strictly prohibited to put it directly into water for cleaning. It should be wiped with a clean soft cloth. The optical surface should not be bumped or scratched.
5. The instrument should be stored in a dry place without corrosive gas.
6. Avoid the loss of spare parts.

The refractometer series are based on the principle that the refractive indices of liquids change when the concentration change. It’s portable, easy, quick and no battery required, easier and more accurate than a traditional hydrymeters, more affordable than a digital meter. It’s a perfect tool for adult or young, home or professional use.

It features high-quality optics with smooth focusing. Its main body is made of aluminum alloy. The internal optical lens with high refractive index make up the precision optical system.The instrument is resistant to abrasion and corrosion, can be used to measure the general corrosive liquid. (But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. )
