AR4 Abbe Refractometer
Precision Measurement for Laboratory Applications
The AR4 Abbe Refractometer is a high-precision optical instrument designed for measuring the refractive index and Brix values of liquid and solid samples. This classic laboratory tool allows users to manually set scales using a drive knob and read values through an eyepiece. Equipped with an integrated digital thermometer, the AR4 displays temperature readings on an LCD screen. For enhanced accuracy, the refractometer can be connected to a PT31 circulation thermostat, ensuring temperature stability during measurements.
The AR4 is ideal for a wide range of applications, including identity verification, purity analysis, concentration determination, and sugar content measurement. It is widely used for quality control in raw materials, semi-finished products, and final goods, making it an essential instrument for food, beverage, pharmaceutical, and chemical industries.
