Abbe refractometer AR4

analoglaboratoryfor the food industry

The 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. Basic functions 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 Abbe refractometer – Temperature control with the circulation thermostat Absolutely independent of the ambient temperatures, accurate and reproducible measurements can be achieved with circulation thermostats in the Abbe refractometer. The PT31 circulation thermostat is small and very easy to connect.
