In the chemical industry, sulfuric acid has become a necessary product and catalyst for everyday factories. The concentration of sulfuric acid is a good and bad standard for controlling a product, so we must constantly check the concentration of sulfuric acid. There are many ways to detect sulfuric acid concentration, but most companies use the principle of double decomposition, and then use titration to calculate the concentration according to the amount of the substance of the reactants. According to the amount of sulfuric acid substances calculated after titration, the quality is converted. Then calculate the quality score. Most of these methods are cumbersome, have poor reproducibility, and have a large workload.
The concentration of sulfuric acid solution is related to many physical quantities such as conductivity , refractive index, etc. Therefore, in principle, the change of one physical quantity can be used to represent the concentration change. A commonly used instrument for the determination of sulfuric acid concentration utilizes a refractive index meter that measures the critical angle. ATAGO handheld sulfuric acid refractometer is based on measuring the refractive index of sulfuric acid, according to the refractive index and concentration of the table (automatic correction of temperature on the refractive index effect), QR-HSO inhaled digital sulfuric acid refractometer is specifically designed for industrial Measurement of sulfuric acid, chemicals, etc. Can be single-handedly operated, avoiding contact with sulfuric acid in both hands to measure the concentration of the use of safe and simple structure, compared to other principles of the concentration meter, its cost-effective, cost savings.
ATAGO's QR-HSO inhaled digital sulfuric acid refractometer can meet the testing needs.
1, high-definition digital display, accurate and direct;
2, factory calibration and automatic temperature compensation, accurate measurement, simple operation;
3, small size design, easy to carry and use a small space;
4, can withstand strong acid and weak acid durable;
Sulfuric acid is a very important chemical production raw material used in the production of different chemicals, such as: production of chemical fertilizers; production of phosphoric acid, hydrochloric acid; synthesis of sulfur-containing compounds (dye, softener, surfactant, fiber, pharmaceuticals , plastic, etc.); and the production of viscose rayon; the production of titanium oxide (paint factory); sulfate (glass and detergent products) and the production of aluminum sulphate; battery battery acid; desiccant; steelworks Acid tank.
The chemical formula of sulfuric acid is: H2SO4 , 99.99% sulfuric acid, colorless, odorless, oily liquid with strong water absorption, capable of mixing with water in any ratio, and releasing a large amount of heat during mixing. Sulfuric acid and oleum can instantaneously damage any cotton fabric. Concentrated sulfuric acid is used to absorb SO3 and then diluted with water to adjust to the desired concentration. Therefore, it is necessary to monitor the sulfuric acid concentration in this adjustment process.
