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.
