VAISALA POLARIS
Polaris™ PR53M PTFE-Body Process Refractometer
The Vaisala Polaris PR53M PTFE-body process refractometer is designed to measure concentrations of aggressive chemicals, such as hydrochloric acid (HCI), sodium hydroxide (NaOH), sodium chloride (NaCl), and sulfuric acid (H2SO4) in the chemical and semiconductor industries.
The integrated ultra-pure PTFE flow cell has no metallic wetted parts, minimizing contamination risk and making it suitable for contact with aggressive chemicals. The PR53M can be mounted to ½ inch process lines with a standard NTP-threaded connection.
• Non-metallic wetted parts, integrated ultra-pure PTFE and sapphire flow cell for demanding environments

- The optical measurement is based on the refractive index (RI).
- The RI can be measured from practically any liquid, and it responds to dissolved material. Because bubbles, particles, or crystals in the process do not affect the measurement, the RI allows accurate measurement for different chemicals, as well as slurries.
- Typical applications include different chemical mixing and monitoring installations in the fine chemical and semiconductor industries.
- In addition to a wide selection of product options, Vaisala offers the possibility to customize the product for specific needs.
- The outstanding longterm stability provides years of accurate, continuous, fast, and stable concentration measurement directly in the process stream.
- Inline process refractometers are easy to install and have no moving parts that require regular maintenance.
