Atago Automatic Digital Refractometer RX-5000α-Plus

The NEW RX-5000α (alpha)–Plus features improved accuracy over the RX-5000α–Plus, with Brix ±0.01 and nD ±0.00002. The RX-5000α–Plus is an automatic digital refractometer which can set measurement temperature internally and has the following features for measuring the refractive index, Brix or concentration of various liquids accurately and speedily

• Since the RX-5000α–Plus has a thermo-module to control temperature, a constant temperature water bath is not necessary
• The measurement starts automatically after the sample reaches your targeted temperature. • The refractive index and Brix at your targeted temperature are speedily displayed
• High Brix ± 0.01% and refractive index ± 0.00002 accuracy can be obtained
• The RX-5000α–Plus displays the top-and-bottom-limit-bar for your set control range
• If the measurement value differs from that of your Standard Liquid or the other refractometer, it can be adjusted in a certain range
• 60 kinds of user scales can be input according to your sample
• The RX-5000α–Plus is capable of calling up 30 latest measurements
