ABBE Refractometer
AR Series

ABBE REFRACTOMETER, MODEL AR 4D
Only a small quantity of sample is needed when measuring with the AR 4D. It is perfect for solid, viscous and liquid samples (transparent or opaque). Measures refractive index (nD), dispersion (nF-nC) and concentration in Brix. Measures by the Abbe principle.

FEATURES
  • Scale illumination
  • Readings via scale window and ocular
  • LED-illumination (590 nm) for prism
  • Adjustment made by cross-hairs
  • Measurement range: Sugar Scale: 0-95% brix; Refractive Index: nD 1.300-1.70
  • Scale Division: 0.0005 nD: 0.25% brix
  • Accuracy: 0.0002 nD: 0.1% brix
  • Prism can be temperature-controlled
  • Adjustable scale
  • Thermometer
  • Tools for adjustment
  • Contact liquid
  • Calibration glass block with engraved refractive index

ABBE REFRACTOMETER, MODEL AR 3D
Accessory and measurment range is the same as for AR 4D, but without LED-illumination for prism. Scale illumination is included.

ABBE REFRACTOMETER, MODEL AR 6D
As for AR 4D, but with a digital thermometer (0 - 100°C), resolution 0.1°C.


ABBE REFRACTOMETER, MODEL AR 4
Readings are made via the ocular
 
FEATURES
  • With scale illumination
  • LED illumination (590nm) for prism and scale
  • Adjustment made by cross-hairs
  • Measurement range: Sugar Scale : 0-95% brix; Refractive Index: nD 1.300-1.700
  • Scale division: 0.0005 nD:0.25% brix
  • Accuracy: 0.0002 nD: 0.1% brix
  • Prisms can be temperature controlled
  • Thermometer
  • Adjustable scale
  • Tools for adjustment
  • Contact liquid
  • Calibration glass block with engraved refractive index

ABBE REFRACTOMETER, MODEL AR 3
Same as AR 4, but without LED illumination for  pism and scale, read via ocular instead of scale

ABBE REFRACTOMETER, MODEL AR 6
Same as AR 4, but with a digital thermometer (0-100ºC); 0.1ºC accuracy, read via ocular instead of scale

ABBE REFRACTOMETER, MODEL AR 51/52
Equipment the same as for the AR 4, but with flow-through cell which can be temperature-controlled by a circulating thermostat bath. The flow-through cel is ideal for quick and easy sample change, and for the measurement of volatile liquids or solutions containing alcohol.
