Atago RX-DD7α-Tea Automatic Digital Refractometer (0-5 Brix)

The RX-DD7α-TEA is Atago's optimized version of the Alpha series automatic digital refractometer for low-concentration applications. Designed to operate within a narrow and low measurement range of 0.000-5.000 Brix, it delivers superior resolution and accuracy compared to standard instruments when analyzing low Brix samples such as green tea, black tea, oolong, and light-sugar beverages.

The instrument operates with automatic temperature compensation (ATC) and provides stable measurement results within the 15-30°C ambient temperature range. The 0.001% Brix resolution and ±0.005% accuracy represent laboratory-grade performance metrics achieved in controlled temperature environments. It is equipped with the standard RX-α/DD-7 series display.

Its specialized low-concentration range design ensures more precise readings within this band compared to general-purpose refractometers measuring higher Brix values. Suitable for tea producers, quality control laboratories, and beverage research and development units.
