KPR-2000 Precision Refractometer

Features

Minute sample size (3 dia. x 1t mm) can be measured!
Minute sample size (3 dia. x 1t mm) can be measured

  • Just load a sample and press the Start button. Automatic measurement starts at the preset conditions by the personal computer that displays the measured data at once.
  • Automatic photoelectric detection and computerized control achieve high accuracy and repeatability.
  • Measurement at three wavelengths in just one minute.
  • The Energy distribution graph is useful to estimate the existence of double refraction.
  • The use of a refractive liquid between the sample and the V-block prism makes it possible to measure the sample with frosted surface if the two faces are machined to 90-degree.
  • Easy operation by the mouth to select measuring parameter.
  • Up to ten wavelengths can be added, allowing the operator to select the required wavelength easily.(Note.1)
Note1：Some wavelength combinations may be unavailable.

Applications

Refractive index measurements for transparent liquids and transparent samples such as new materials and glass. Birefringence presumption.

Operation Screens
