The AR2008 is an Abbe refractometer in which the sample is placed between a measuring and illumination prism. The device can measure the refractive index or Brix value and display the measured value together with the temperature on the LED display. Using the serial interface, the measured values, date and time can be transferred directly to a PC or printed. To ensure temperature control the refractometer can be connected to a circulation thermostat. These devices can be used in a wide range of applications: e.g. in the chemical, petrochemical, oil and grease industries, the food industry, in the pharmaceutical environment and in research & education.
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
- Digital representation of the measurement data
- Integrated thermometer
- Hose connections for temperature control with a circulation thermostat
- Automatic temperature compensation for the BRIX scale can be switched on as an option
- Robust housing and easy handling
- Serial interfaces for coupling with PC or printer (RS-232, RS-422)
