Phosphoric acid is produced by mining the naturally occurring phosphate rock and processing it via a wet process or a thermal process. The concentration of the acids during the wet process can be measured inline with the process refractometers, such as those manufactured by K-Patents.
To learn more about where and how these refractometers are used in wet process phosphoric acid production, visit the PSI Controls web page.
