The principle of the refractometer is to obtain the concentration of the liquid based on the comparison of the refraction angle.
A refractometer is also called a refractometer. When light passes through liquids of different concentrations, different refraction angles will be produced. The liquid concentration value can be obtained by comparing the refraction angles. The refractometer is designed based on this principle. The sugar meter is used to quickly determine the concentration of sugar-containing solutions and other non-sugar solutions, and is widely used in sugar, food, beverage and other industrial sectors as well as agricultural production and scientific research. It is suitable for the concentration measurement of various sauce (seasoning) products such as soy sauce and tomato sauce, the sugar content measurement of products with high sugar content such as jam, syrup, liquid sugar and various fruits, and the production line of fruit juice, refreshing drinks and carbonated drinks , quality control, pre-delivery inspection, etc., in the process of fruit from planting to sales, it can determine the exact harvest time, for sweetness classification... In addition, it is also widely used in the concentration determination of textile industry pulp Applications. It can also be used to control the concentration of various industrial solutions (such as cutting fluid and grinding fluid). The hand-held sugar meter series products produced and sold by our factory have various measurement ranges. Simple structure, shockproof, easy to operate and carry, clear vision, etc., can meet the requirements of different customers. The products are available in wholesale and retail at low prices, reliable in quality and diverse in variety.
How to use: Open the cover and carefully wipe the detection prism with a soft cloth. Take a few drops of the solution to be tested, place it on the detection prism, and gently close the cover to avoid the generation of air bubbles, so that the solution spreads over the surface of the prism. Aim the light inlet plate of the instrument at the light source or a bright place, observe the field of view through the eyepiece, and turn the eyepiece adjustment handwheel to make the blue-white boundary line of the field of view clear. The scale value of the dividing line is the concentration of the solution.
Precautions This instrument is a precision optical instrument, and the following items should be paid attention to during use and maintenance:
• Be careful and cautious during use, use strictly according to the instructions, do not loosen the connecting parts of the instrument arbitrarily, do not drop, collide, and violent vibration is strictly prohibited.
• After use, it is strictly forbidden to wash in water directly, and should be wiped with a clean soft cloth. The optical surface should not be scratched or scratched.
•The instrument should be kept in a dry place without corrosive gas.
• Avoid loss of spare parts.
