Automatic Digital Refractometer RX-5000α

The RX-5000α (alpha) 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 (alpha) 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 ± 0.03% and refractive index ± 0.00004 accuracy can be obtained.
• The RX-5000α (alpha) 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 (alpha) is capable of calling up 30 latest measurements.
*Special model of RX-5000α allows pre-programming of an additional scale (such as honey moisture, inverted sugar%, salt concentration or butyro) in addition to Refractive Index and Brix (%) at customer's request.
This product comes standard with a two (2) year limited warranty against manufacturer’s defects from the date of the original purchase. The warranty period can be extended to three (3) years if the product is registered with ATAGO.
FDA 21 CFR Part 11 Software Included in Standard Delivery.
