Vaisala Polaris PR53W Valve-Body Process Refractometer
Safely and accurately measure the concentrations of aggressive chemicals such as sulphuric acid (H₂SO₄), hydrochloric acid (HCI), sodium hydroxide (NaOH), and hydrofluoric acid (HF) in the chemical, biochemical, mining, and metal refining industries. The Vaisala Polaris PR53W Process Refractometer is the ideal choice for measuring aggressive chemicals in large pipelines, thanks to its extreme chemical resistance and durability in even the harshest environments.
Mounted in a membrane-lined valve body with no metallic wetted parts, the PR53W process refractometer is easy to install via convenient flange mounting to 1 and 2 inch ANSI and DN50 and DN25 flanges. With this instrument, you can perform inline measurements with confidence, knowing that it can handle even the most challenging reagents.

Description
Aggressive chemicals in mining and metal refining
Measure safely and accurately concentrations of hydraulic fluids, cutting oils, cooling lubricants and washing liquids in metalworking and machining, polyalkylene glycol (PAG) quenchant in metal induction hardening and stainless-steel passivation process.
Key Benefits
-
For the most aggressive chemicals
Integrated ultra-pure PTFE lined valve body has no metallic wetted parts making it fully suitable to be in contact with aggressive chemicals. -
Widest concentration curve library
Vaisala’s application base for chemical industry is astonishing, currently we offer over 500 different concentration curves, and the library is ever-growing. Start your measurement with factory pre-installed concentration curve, just install and enjoy accurate measurements. -
Customizable product with our Engineer to Order service
In addition to wide standard process connection offering, Vaisala offers an opportunity to customize the product to meet specific processing needs whether it is a special process connection, wetted parts material, custom size flanges or custom type enclosure for transmitters (Ex d/Ex p). Contact us for options! -
Plug & play to Indigo
The process refractometers can be connected to Vaisala Indigo520 transmitter to expand features, including data storage, graphical interface, analog and digital interface. - Always accurate, no drift
The measurement is based on optical measurement of the refractive index (RI). The RI can be measured from practically any liquid or slurry, and it is sensitive to dissolved material. Bubbles, particles or color do not affect the measurement.
