By choosing the long probe Vaisala Polaris PR53AP sanitary probe process refractometer you choose to buy a reliable, modern and modular product platform that is safe to use in food and beverage manufacturing, has 3-A and EHEDEG certifications and meets all hygienic demands.
The PR53AP model is suitable to use in high heat, with scrapers and mixers and in sticky process conditions. It is also compatible with clean-in-place (CIP) and sanitation-in-place (SIP) systems. Connectivity options include mA, HART, and Modbus RTU as a standard.
Key benefits
3-A Sanitary and EHEDG certified
Hygienic certification guarantees that all hygienic demands are met, and sanitary features are woven into the product design. The product is safe and suitable to use in food and beverage processing.
Full measurement range
The measurement range for concentration/Brix is 0-100 %.
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.
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).

Easy installation, easy and low maintenance
Convenient installations directly to different size process pipes with standard sanitary and VARINLINE® couplings, or with a sanitary flow cell with measurement data incorporated to control system. Vaisala also offers miniature flow cell for bypass lines or sample lines, suitable for example in pharmaceutical manufacturing.
Process refractometers are easy to install and low maintenance instruments. The optical measurement principle combined with an instrument with zero moving parts does not require regular maintenance.
Outstanding durability
The outstanding long-term stability and the measurement principle with no moving parts provides years, even decades of accurate, continuous, fast and stable measurement for concentration of sugar (Brix) and various other chemical concentrations directly in the process stream.
Maximum productivity and safety in hazardous areas
The industry-leading Vaisala Polaris process refractometers offer Ex-certified product versions for hazardous areas.
Depending on selected product option, the refractometers are designed to be installed in either
IECEx/ATEX Zone 0/1 (North America Class 1 Division 1) or Zone 2 (Class 1 Div 2).
The Polaris Ex-versions are Indigo520 compatible to secure maximum productivity.
The Indigo520, and the associated IS equipment in case of Zone 0/Class 1 Div 1, is placed in the safe area.
