This model eye is ideal for teaching and practice. The pupil diameter and refractive error can be set exactly and are therefore reproducible. The front lens compartment holder accepts up to two trial lenses. The cylinder can be read from the graduated scale.

• Scale: 0° – 180° for cylinder determination.
• Diameter of pupil. Variable 2, 3, 4, 5, 6, 8mm.
• Optics: Optical glass, achromatic lens, focal length F = 32mm.
• Trainer body. Made of metal – Extremely

The spectacle-mounted indirect ophthalmoscope to suit any pupil size. Two separate controls for selecting the ideal setting of parallax and convergence guarantee completely illuminated stereo views in pupils up to 2 mm, as well as viewing in the periphery.

The KRÜSS DR201-95 is a compact, mobile and splash-proof digital handheld refractometer. It is used to measure the refractive index (nD) and the sugar content in % (%Brix) of liquid and viscous samples. Thanks to the automatic temperature compensation for the BRIX scale, a reproducible measurement can be achieved even under changing ambient conditions. The automatic temperature compensation for the BRIX scale supports the user when measuring sugary drinks and confectionery. The device is splash-proof and meets the IP64 standard. The DR201-95 is used in the food and beverage industry, in pharmacies, laboratories and testing laboratories as well as in research and teaching.

Basic functions

• Measurement range: nD 1.3330-1.5318 and 0-95%Brix
• Mobile automatic measurement at the touch of a button
• High measurement accuracy: nD ±0.0003 and ±0.2 %Brix
• Reproducible measurement results that are not dependent on the user’s interpretation.
• Automatic temperature compensation (BRIX scale)
• Swift filling and cleaning
• With high-quality, fully chrome-plated measurement tray
• Robust housing and low device weight
