Description
1.
Main Technical Parameters:
Measuring Range and Minimum Scale: Brix: 0-40% Minimum Scale: 0.2% Alcohol: 0-25% With temperature compensation, it can overcome data deviations caused by temperature changes and make the data more accurate. The eyepiece has been improved; the objective glass is heavy crown optical glass, not ordinary glass, which provides greater clarity and reduces observer fatigue. 2. How to Use: 1) Align the refracting prism with the direction of the light and adjust the diopter angle ring until the marking line is clear; 2) Adjust the benchmark: Before measuring, prepare the calibration solution (pure water). Ensure the instrument and the liquid to be tested are at the same temperature. Open the cover. Then, take 1 to 2 drops of standard droplets onto the refractive prism and gently press the cover with your hand to create a dividing line between light and dark. Turn the calibration screw to align the light-dark dividing line in the eyepiece's field of view with the reference line (0%). Note: This optical instrument has been factory-calibrated and is ready for immediate use. 3) Open the cover. Clean the prism surface with a soft cloth. Take 1 to 2 drops of the solution to be tested onto the refractive prism. Replace the cover and press gently. Read the relative scale of the light-dark dividing line. This indicates the measured solution's concentration and density values. 4) After measurement, wipe the prism surface and cover plate directly with a damp cloth and store properly after drying. Correction: The instrument must be zero-calibrated before measuring. Take a few drops of distilled water, place them on the detection prism, and turn the zero adjustment screw to set the dividing line to the 0% position on the scale. Then clean the inspection prism and proceed with the inspection. Some instrument models require a standard solution instead of distilled water for calibration. Precautions: This instrument is a precision optical instrument. The following points must be considered during use and maintenance: 1. Care must be taken during use. Use it strictly according to the instructions and do not arbitrarily loosen the instrument's connecting parts. Do not drop it, collide with it, or subject it to violent vibrations. 2. After use. It is strictly forbidden to put it directly into water to clean it. It must be wiped with a soft, clean cloth. The optical surface must not be bumped or scratched. 3. The instrument must be stored in a dry, non-corrosive place.
