Measure safely and accurately the concentrations of aggressive chemicals: sulphuric acid (H₂SO₄), hydrochloric acid (HCI), sodium hydroxide (NaOH), and hydrofluoric acid (HF)

Measure the most aggressive chemicals inline in chemical industry, and in industries, where aggressive reagents are used, such as chemical, biochemical, mining and metal refining. The Vaisala Polaris PR53W Process Refractometer is the perfect choice for large pipelines to measure aggressive chemicals as it has extreme chemical resistance and just plain durability in the harshest environments.

The PR53W process refractometer is mounted in a membrane‑lined valve body, with no metallic wetted parts included. This allows convenient flange mounting to 1 and 2 inch ANSI and DN50 and DN25 flanges.
