Refractometer: IRM-11 Refractometer

The inline refractometer IRM-11 continuously and precisely measures the concentration of substances such as sugar or salts in liquids. This enables the determination of the alcohol content, the blending ratio of juices, mixed drinks and soft drinks, or the dry matter in milk products.
The inline analysis of the concentration with IRM-11 by determining the °Brix, °Plato or refractive index value nD offers particular advantages. In many applications measurements are taken using a hand refractometer. To avoid deviations in product quality, these manual measurements must be carried out at very short intervals, often every 20 minutes. The measurement with IRM-11 takes place fully automatically at the desired time interval (adjustable from 2 s). This leads to a substantial working time and cost saving potential and reduces the risk of product loss between two measurements.

Main features and benefits:

  • Very compact (ø 66 mm, 480 gr.), front flush refractometer with simple inline integration without bypass
  • Fully automatic measurement in the desired intervals (adjustable from 2 sec), saving up to 1 man-hour of working per shift.
  • In the case of manual measurement, the entire product produced between measurements, e.g. every 20 minutes, may be defective. IRM-11 can avoid product losses by its permanent measuring method
  • Fully temperature compensated for precise results even with rapid changes
  • The simple installation guarantees precise measurement already during mixing in the tank or exact adjustment during the running process/li>
  • Process temperature up to 100 °C continuous, CIP/SIP cleaning up to 140 °C / 60 min.
  • Long-life LED light source with highly resistant sapphire optics
