Safe and Accurate Inline Sulfuric Acid Measurement Improves Quality and Production

Relevant for fertilizers, acid production, sulfates, sulfonates, glass, detergents, batteries, Pickling baths, and many more

Sulfuric Acid and Oleum: All with one Instrument

The only single sensor capable of measuring the entire range of H2SO4 and Oleum!  Sulfuric acid is one of the most important industrial chemicals used in the world and found in many completely unrelated industries. Anton Paar offers several inline process solutions tailored to all kinds of applications.

Aluminium and Steel Mills

Remove scale and not base material. More accurate pickling bath concentration saves resources and time while improving quality and revenue.


Charged with monitoring acid concentration Anton Paar's Acid Monitor is fundamental in final battery quality, recycling used acid and automating production.


Clean and accurate concentration measurements improve cleaning properties and quality with increased efficiency and reduced production costs.


Harvest production savings! Improved sulfate and nitrate accuracy saves resources and increases production, quality and revenue.

Many More

While used in industries too numerous to mention, sulfuric acid measurement remains the same. Anton Paar’s Sulfuric Acid Monitor allows for highly accurate and
