Measurement Principles

The refraction of light is a phenomenon wherein the direction that light is traveling changes as it passes through different mediums.
Through this phenomenon, we can observe as light’s direction changes and the “bent” appearance of substances even in the seemingly familiar, ordinary places in our day to day lives.
For example, imagine the lens of a pair of glasses and a pool.
When looking through the lens, an object appears larger or smaller than it is in reality.
When standing inside a pool, as you peer downward from the water’s surface, your legs will look shorter than they actually are.
As light moves from medium A (in this case, air) to medium B (lens and the pool’s water), it refracts.
Furthermore, it is known that light’s refraction changes depending on the concentration of a liquid.
The refractive index, which is a value that expresses the degree of refraction, is proportional to the density (mixture ratio) of a component.
Therefore, if there is 10g of sugar contained in 100ml of an aqueous solution and 20g of sugar contained in 100ml of an aqueous solution, the latter will have a higher refractive index value.
This difference in refractive index due to concentration variance has also been confirmed in solutions other than sucrose.
The properties of both the phenomenon known as the refraction of light and differing refractive index depending on concentration, are used as the principles of refractometers.
In addition to measuring the refractive index of a liquid, refractometers also display the concentration, converted from the refractive index.

Product introduction

Polyaluminum chloride, referred to as PAC, is a kind of flocculant, commonly found in sewage treatment plants, is a new type of inorganic polymer flocculant, is an efficient, fast, low-consumption water treatment agent. In the water, the negative charge carried by the colloidal particles instantly neutralizes the effect, destabilizes the colloid, and the colloidal particles are rapidly flocculated, and further bridged to form large flocs and precipitate rapidly. And further bridged to generate large flocs and rapid precipitation.

Aluminum chloride inline refractometer analyzer, also known as aluminum chloride inline refractometer, aluminum chloride inline refractometer meter, is a high-precision optical instrument that measures the refractometer of solution based on the principle of light refraction and total reflection. The inline refractometer analyzer is installed on the production line to detect the samples flowing through the pipeline or tank of the production line to ensure the sample qualification rate and the normal operation of the production process. Through inline instruments and automated production equipment, it helps enterprises improve production efficiency, manual automation, reduce labor costs, reduce production costs, and effectively ensure the uniformity and stability of product quality.
