Classical, visual refractometer designed for the determination of the refractive index of liquid media with high or low viscosity. It is used in the fast control of liquids and the in-field analysis. The measuring principle is based on the law of Snellius (law of refractive index) and is able to measure with transmitted or totally reflected light. With a contact fluid even solids can be measured with the ABBE refractometer.
- With hose connections at the prism unit for the thermostatisation of the optical parts.
- Temperature is measured with a digital thermometer.
- Simple handling.
- Small sample volume necessary.
- Optional: illumination unit for prism and scale illumination with a red LED.
