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. Particles, bubbles 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 wetted parts material, custom size process connections or custom type enclosure for transmitters (Ex d/Ex p). Contact us for options!

  • Easy installation, easy and low maintenance
    Convenient installations directly to different size process pipes with standard sanitary and Variline 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.
