• Determination of concentration and purity control of liquid media with high or low viscosity and solids
• Simple handling
• Small sample volume necessary
• Can be temperature controlled by a circulating thermostat bath

The SCHMIDT+HAENSCH ABBE refractometer AR12 is a classic, visual refractometer, named after its inventor Ernst Abbé and 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 refractometer is equipped with hose connections at the prism unit for temperature control of the optical parts. The temperature is measured with a digital thermometer. 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.

Optionally an illumination unit is available for prism and scale illumination with a red LED.
