RX-5000αB Automatic Digital Refractometer

RX-5000αB Automatic Digital Refractometer


RX-5000α-Bev is a new type of automatic digital refractometer suitable for beverages. This reliable digital device with an excellent quality-price ratio is a complete and versatile tool, very easy to use and therefore essential for all control laboratories. A flat sample stage replaces the sample well for easy sample wiping and for easy cleaning.

It is enough to take 1 ml of sample to almost immediately obtain the refractive index, alcohol or sugar concentration with an extremely precise display (5 digits after the decimal point).

Since it has a thermal module to control the temperature, a constant temperature water bath is not necessary.

The measurement starts automatically after the sample reaches your target temperature.

The refractive index and Brix at your target temperature are displayed quickly.

The accuracy of Brix index of ±0.03% and refractive index of ±0.00004 can be achieved.


  • Multiple scales: 60 kinds of user scales can be entered according to your sample
  • Wide measuring range
  • Digital LCD display
  • Memory of the last 30 measurements
  • The special model of the RX-5000α allows an additional scale (such as honey moisture, inverted sugar %, salt or butyro concentration) to be pre-programmed in addition to refractive index and Brix (%) to ask when ordering


  • Measurement ranges: Refractive index (nD) from 1.32700 to 1.58000 / Brix from 0.00 to 100.00% (many other configurable scales)
