Detector Alcohol Er Refractometer 0-40% Alcohol 0-25%

Description First, the main technical parameters: Measuring range and minimum scale: Brix: 0-40% Minimum scale: 0.2% Alcohol: 0-25% With the function of temperature compensation, it can overcome the data deviation caused by temperature changes and make the data more accurate. The eyepiece is upgraded. The lens glass is heavy crown optical glass, not ordinary glass, which has higher clarity and reduces the fatigue of the observer. 2. How to use: 1) Align the refracting prism with the direction of the light, and adjust the diopter ring until the marked line is clear; 2) Adjust the benchmark: Before measurement, make the temperature of the standard solution (pure water), the instrument and the liquid to be measured the same. Open the lid, take 1~2 drops of standard droplets on the refractive prism, press the lid lightly with your hand, and draw the dividing line between light and dark. Turn the calibration bolt to make the light-dark dividing line in the eyepiece field coincide with the reference line (0%); Note: This optical instrument has been adjusted before leaving the factory and can be used directly. 3) Open the lid, wipe the surface of the prism with a soft flannel, take 1~2 drops of the solution to be tested on the refractive prism, cover the lid and press lightly, read the relative scale of the two dividing lines, that is, the measured The concentration value and density value of the liquid in the solution. 4) After the measurement, directly wipe off the attachments on the prism surface and the cover plate with a damp flannel, and store it properly after drying. Correction The instrument needs to calibrate the zero point before measurement. Take a few drops of distilled water, put it on the detection prism, turn the zero adjustment screw, and adjust the dividing line to the 0% position of the scale. Then clean the inspection prism and inspect it. Some models of instruments require standard solutions instead of distilled water for calibration. Precautions This instrument is a precision optical instrument, the following matters should be paid attention to in the use and maintenance: 1. Be careful when using it, use it in strict accordance with the instructions, do not loose the connecting parts of the instrument at will, do not drop, collide, and strictly prohibit violent vibration. 2. It is strictly forbidden to directly put it into water for cleaning after use. It should be wiped with a clean soft cloth. For optical surfaces, there should be no bumps or scratches. 3. The instrument should be stored in a dry, non-corrosive place. 4. Avoid the loss of spare parts. Three, product application The refractometer has the advantages of simple structure, shockproof, convenient operation, convenient carrying, clear vision and low price. Sugar series is used in canned food, fruit juice manufacturing, wine fermentation, beverage, fruit, honey picking and other fields.
