There are different PR53 refractometer models. Each model is adapted for different process requirements.

  • The Vaisala Polaris PR53AC sanitary compact process refractometer is designed to measure liquid concentrations, such as Brix.
  • The Vaisala Polaris PR53AP sanitary probe process refractometer is designed for food and beverage, dairy and brewery industry customers, and OEMs to measure liquid concentrations, such as Brix, in applications such as jam cookers and mixing tanks.
  • The Vaisala Polaris PR53GC general-purpose compact process refractometer is designed for measuring concentrations of acids, alkaline solutions, alcohols, hydrocarbons, solvents, and various other solutions.
  • The Vaisala Polaris PR53GP general-purpose probe process refractometer is designed for measuring concentrations of sugars/Brix, acids, alkaline solutions, hydrocarbons, solvents, and various other solutions.
  • 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 retractable Vaisala Polaris PR53SD Safe‑Drive process refractometer is designed for safety‑critical measurements in pulp mills, such as firing liquor concentration. The Safe‑Drive system with a PR53SD refractometer enables safe sensor insertion and removal also when the process line is in full operation.
  • The Vaisala Polaris PR53W valve-body process refractometer is designed to measure concentrations of aggressive chemicals, such as sulfuric acid, hydrochloric acid (HCI), and sodium hydroxide (NaOH) in production pipelines such as in the chemical, biochemical, and pharmaceutical industries.

PR53AC and PR53AP have been designed to be used in food contact applications and meet the 3‑A and EHEDG sanitary standard requirements.
