Anderson Negele - IRM-11 Refractometer

  • Measurement of dissolved particles in liquids
  • Stainless steel version 316L / Optic Sapphire glass
  • Measurement in BRIX. Plato, Refractive Index or customer specific scale
  • IRM-11 is FDA and 3A approved

Product description

With IRM-11 it is possible to measure dissolved particles in liquids with refractive index scales such as BRIX, Plato or other customer-specific devices.

An LED light source radiates directly into the medium. The density of the liquid affects the speed of light and changes the refractive value.

Refraction = Refraction of light beam at the transition between two materials / media with different refractive index

The receiver section reads the temperature compensated refractive value and displays the value via a 4-20mA signal in the selected unit.

Examples of application:

  • Measurement of sugar concentration
  • Measurement of the alcoholic content of brewing, distillery and wine making
  • Brix based blend control in juice production

Other features:

  • Front flush ensures easy cleaning and quick response to product changes
  • CIP up to 140 ° C for a maximum of 60 minutes.
  • Compact instrument exclusively in stainless steel and optics in sapphire glass.
  • Analog output 4-20mA, freely adjustable.
  • FDA and 3-A approved
  • Status indication with LED
