basic information
In industries where strong chemical agents are used, such as chemical manufacturing, chemistry, biochemistry, mining, and metal refining, the most potent chemicals are measured inline. The Vaisala Polaris PR53W process refractometer is ideal for measuring strong chemicals in large pipelines due to its high resistance to chemicals and pure durability in the harshest environments. The PR53W process refractometer is mounted on a membrane-backed valve body and contains no metal wetted parts, allowing for convenient flange mounting to 1 and 2-inch ANSI, DN50, and DN25 flanges.
