The KRÜSS AR4 is a classic Abbe refractometer. The scales can be set manually using the drive knob and the refractive index and Brix values are read off using an eyepiece. The temperature is measured with the integrated digital thermometer and displayed on the LCD. The AR4 refractometer can be connected to a circulation thermostat for temperature control. This device can be used in a wide range of applications: for identity checking, purity control and concentration determination of raw materials, semi-finished products and end products or for determining the sugar concentration as well as for incoming and outgoing goods inspection.

Measurement of liquid and viscous samples, regardless of their viscosity
Measurement of films possible and of solid samples that have at least one smooth side
Wide measurement range from nD 1.3000-1.7200 and 0-95 %Brix
Reading the measured values via an eyepiece
Integrated thermometer
Hose connections for temperature control with a circulation thermostat
Robust housing and easy handling
Temperature display on LED display

The Abbe refractometers have a wide range of applications in the chemical, petro-, oil- and fat industries, in the food industry, in hospitals, pharmacies and research offices, as well as in research and teaching. The special feature is the possibility to measure not only liquid and viscous samples but also solids and foils.

Main application fields are:

Identity test, purity control and concentration determination of raw materials, semi-finished products and end products
Determination of the sugar concentration
Incoming and outgoing goods inspection
Purity control
Testing of food and pharmaceutical products
Testing of the compliance with national and international standards
Training
