Method for determining the concentration of sodium hydroxide - Master's thesis - Dissertation

Sodium hydroxide solution is used in many production processes. It can be said that without sodium hydroxide, it is impossible to produce thinner, plastic, bread, textiles, inks, pharmaceuticals, pigments, and the like. When you drink the beverage in the beverage bottle, the plastic bottle recycling equipment also uses sodium hydroxide solution to clean the beverage bottle. Similarly, the canned oil bottle, oil tank and milk bottle in life are also used.

The products mentioned above are not premised on the use of an accurate concentration of sodium hydroxide solution, because only the concentration is accurate to ensure that the quality of the product is consistent. The conventional method for detecting the concentration of sodium hydroxide solution is titration. The titration method is a long-time, high-volume detection method, and it is also a detection method with low detection accuracy. Developed and produced by ATAGO

Sodium hydroxide concentration meter

It can quickly and reliably help you measure the concentration of sodium hydroxide solution. The refractive index of the sample can be measured very conveniently by the refractometer, and the concentration is measured by the refractive index. When the sodium hydroxide solution sample is placed in the sodium hydroxide concentration meter, the percentage of sodium hydroxide concentration is directly on the display of the refractometer, which can be directly read, eliminating the time-consuming and laborious data conversion. In addition, refractometers developed and produced by ATAGO are also known as

Concentration meter

Different refractometers can also be designed according to the specific use of the user.

Sodium hydroxide concentration meter

The concentration of sodium hydroxide can be measured, and the measured result shows the actual concentration of sodium hydroxide. The instrument is small, easy to operate, waterproof design, can be washed directly with water after testing.
