These optical analytic sensors from Anderson-Negele continuously measure the refractive index in °Brix, Plato or nD quickly, precisely and automatically.

  • Measurement is taken inline
  • Compact all stainless steel design
  • Monitoring of concentrate or dosing control
  • Simple & quick installation


Integrated process refractors can analyze liquids, fruit preparations and creams in in the beverage and juice industries, dairies, breweries, wine production and other food businesses. The inline analysis of media based on density or concentration offers many advantages in various sanitary applications.


Control of the blending:


Monitor the concentrate, dosage control for a constant sugar content when blending the final product, and quality control in the bottling of various beverages and foods:


  • Juices, syrups, nectars and other mixed drinks
  • Soft drinks and refreshments
  • Energy drinks
  • Jams, jellies and marmalades
  • Creams, fruit preparations and other desserts
  • Other liquid or pasty products


Determination of dry matter:


In many dairies, spray drying is an efficient method to obtain high-quality whey powder from milk or other milk products.


  • If the dry matter content is higher than specified, the cooler can clog and fail, the process is interrupted, and the added value is reduced.
  • If the dry matter content is too low, the end product becomes too dusty and can lose quality and value in subsequent processing.
  • With an inline refractometer, correct concentration in the evaporator can be continuously monitored and controlled during the process.


Measurement of mash concentration and original wort:


Through continuous measurement of the Brix or Plato value during wort boiling, the specified value of the original wort can be monitored.

Refractometers Benefits

All stainless steel design

Quick installation

Control of sanitary process

Control in blending

Glycol control in the primary cooling circuit:

If water enters the glycol circuit due to leaks in the cooling system, this is not visible to the naked eye.


  • The concentration of the coolant glycol can drop too far and thus freeze the tubes of the primary cooling circuit.
  • Repair costs, a complete refilling with glycol mixture and a loss of production can cause high costs as possible consequences.
  • Continuous measurement of the glycol concentration with the inline refractometer ensures automatic, active monitoring of the concentration




The IRM-11 is Anderson-Negele’s in-line refractometer designed for use in dairy, food, and beverage processing applications.
