Robust technology for solving the most challenging tasks of chemical industry

Measure moisture and liquid concentration and ensure unbeaten product quality of your chemicals


Moisture measurement in chemicals production and storage

In chemical industry, moisture analysis is required for ensuring smooth drying operations such as spray drying or vacuum drying. By measuring relative humidity (RH), absolute humidity, dew point and temperature, chemicals manufacturer can be certain there is no quality deviations in the produced powdered chemicals.

Moisture monitoring is also needed in storages of chemicals to preserve the quality of the final product and prevent the risk of chemical reaction and explosion. Humidity control is also crucial for preserving hygroscopic substances and preventing powder caking.

Finally, conditions monitoring, and humidity control are required for ensuring safe environment where glove boxes, reaction chambers and vacuum chambers are used.

Inline liquid concentration measurement for chemicals processing

Measuring liquid concentration or density inline is important in the chemical industry as density variations have impact on both raw materials and finished products. 

Process safety is also mandatory, since hazardous chemicals represent a potential risk to people and the environment. While managing these challenges, chemical manufacturers strive to produce high-quality products that meet customers’ specifications. To achieve these goals, accurate process measurements, high process efficiency, low energy consumption, and state-of-the-art process control management are crucial. 

Have a look at the application examples for references of the use of the inline refractometer technology in chemicals processing.
