20-45% Brix Refractometer Manual Refractometer for Determining Sugar Content of Honey Vegetable Oil Syrup Molasses with ATC Function and Instructions

I. Main technical parameters: measuring range and minimum scale: sugar: 0-40% minimum scale: 0.2%; alcoholic acidity: 0-25%. Second, method of use: 1) Align the refracting prism with the direction of light, adjust the eyepiece aiming ring until marker is clear; 2) Adjust the reference point: first prepare the standard solution (pure water), the instrument and the liquid to be measured at the same temperature before the measure. Lift the lid, then place 1-2 drops of standard solution on the refracting prism and gently press the lid with your hand to obtain a light and dark boundary line. Turn the calibration screw so that the light-dark boundary line in the eyepiece field of view coincides with the reference line (0%); Note: This optical instrument is factory calibrated and can be used directly. 3) Lift the lid, wipe the surface of the prism with a soft cloth, take 1~2 drops of the solution measured on the refraction prism, cover the cover and gently press, read the relative scale of the light and dark dividing line, which is the concentration value and the density value of the measured liquid. 4) After the measurement, wipe the surface prism and cover plate with a damp washcloth and store the device properly after drying. Calibration The instrument requires zero point calibration before measurement . Take a few drops of distilled water, place them on the test prism and turn the zero adjustment screw so that the dividing line is adjusted to the 0% scale position. Then wipe the test prism and perform the test. Some types of instruments require a standard solution instead of distilled water for calibration. Attention This instrument is a precision optical instrument and the following points should be taken into account during its use and maintenance: 1. when using, please be careful, strictly follow the instruction manual, do not arbitrarily loosen the instrument of the connecting parts, do not fall, do not collide, and do not not be subjected to violent vibration. 2) After use, it is strictly prohibited to put the instrument directly into water to clean it, and it should be wiped with a soft clean cloth. 3) The instrument should be stored in a dry, non-corrosive place. 4) Avoid the loss of spare parts. 4. avoid the loss of spare parts. Third, the application of the product The refractometer has the advantages of simple and shockproof structure, easy to use and easy transportation, clear vision and low price. Sugar series are used in canning, juicing, brewing and fermentation, beverage, fruit , honey harvesting and other fields. Salt series are used in the field of seawater breeding, aquarium, preparation of saline, etc. . Medical series are used for detection of serum protein and specific gravity of urine. Industrial series are used for detection of automotive battery fluid, freezing fluid, cleaning fluid, machine tool lubricating fluid and cutting fluid.
