Revolutionise your laboratory with cutting-edge concentration measurement technology

In the fast-paced world of industrial and chemical processes, precision is paramount. Traditional methods for determining the concentration of sulphuric acid, such as titration, involve handling this highly corrosive substance, which poses significant safety risks. Our state-of-the-art combined density and sound velocity meter is a groundbreaking solution designed to enhance accuracy while minimising handling and safety concerns.

Key benefits of our advanced instruments

• Minimal sample requirement: Our meter requires only 3.5 mL of sample, streamlining your workflow by eliminating the need for dilution or preparation steps.
• Rapid measurement: Achieve precise concentration readings in just 0.5 min to 6 min, boosting your efficiency and productivity.
• Durable and reliable: Built to endure even the most concentrated sulphuric acid and oleum, with a measuring range of 0% to 114% sulphuric acid (65% SO3)
• Enhanced accuracy: Incorporates sound velocity measurement to account for the non-linear relationship between concentration and density in sulphuric acid solutions.

Strategic applications across Asia

Our advanced measurement technology addresses critical needs across various sectors including fertiliser production, chemical manufacturing, petroleum refining, metal processing, automotive batteries, and the textile industry.

Versatile measurement capabilities

Our instrument is not limited to sulphuric acid. It excels in measuring binary solutions and offers additional versatility by incorporating sound velocity measurement. This unique capability allows for accurate determination of concentration ranges in solutions where density does not increase steadily. For instance, it effectively measures acetic acid that peaks rather than increases linearly.
Furthermore, our technology is adept at analysing ternary systems, such as formaldehyde/methanol/water or sulphuric acid/nitric acid/water. This is achievable as long as the density and sound velocity of the components vary sufficiently.

Advanced research & development

For research and development applications, simultaneous measurements of density and sound velocity at varying temperatures enable the calculation of further physical properties, providing comprehensive data for diverse scientific and industrial needs. The detailed analysis and precise control offered by our instrument support innovation and optimisation in various fields, from materials science to chemical engineering.
In the spotlight: Sulphuric acid concentration determination
Our advanced combined density and sound velocity meter offers unparalleled precision, safety, and efficiency. By integrating this technology, you can streamline your measurement processes, enhance accuracy, and significantly improve safety when handling hazardous substances.
Figure 2: Density and sound velocity characteristics of sulfuric acid and oleum
Examining Figure 2, it becomes clear that at 40°C, density measurements can accurately determine concentrations ranging from 0% to 90%. However, for concentrations between 90% and 100%, sound velocity is required as density changes very little in this range compared to sound velocity. For free SO₃ concentrations between 0% and 47%, density measurements are used, since sound velocity data do not provide a precise correlation. Beyond 47% free SO₃, the instrument shifts to sound velocity for accurate concentration determination.
The measurement temperature can be set to either 20°C or 40°C, based on the sample’s physical properties. Samples with up to 27% free SO₃ can be measured at 20°C. For samples with higher free SO₃ concentrations, the temperature should be set to 40°C. At 40°C, the instrument’s software can accurately measure concentrations from 0% H₂SO₄ to 65 % SO₃.
