Automatic Digital Refractometer RX-5000α-Plus
- 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.
FDA 21 CFR Part 11 Software Included in Standard Delivery.

FDA 21 CFR Part 11
Software is available to support your FDA 21 CFR Part 11 compliance.
Ergonomically Designed Layout
The RX- a series was designed with ease of use in mind. Extensive research was performed in the design phase to ensure an ergonomic interface that made operation easy while maximizing efficiency.
4 Measurement Mode Options
MODE-1: For maximum accuracy
Displays the measurement value once the sample reaches the target temperature.
MODE-3: For no temperature control
Provides an option to turn the thermo-module off. Without temperature control, the measurement value is displayed in 4 seconds after the START key is pressed.
MODE-2: For fast results
Measures refractive index and temperature at fixed intervals and displays the estimated measurement value at the target temperature.
MODE-S: For emulsion samples
Displays the measurement value once a certain level of sample stability is achieved.

Application Examples
Refractive Index
Refractive Index is a common quality standard measure for pharmaceutical or chemical products. Measurements need to be taken at a constant temperature, commonly 20°C, 25°C, and 40°C. The RX-α units are equipped with the internal Peltier Thermo-Module, and measurement starts once the target temperature is reached.

Brix
Brix is measured for quality control purposes in the food and beverage industries. The RX-α units are widely used for fruit juice, condiments, jams, and honey. The RX-007α (minimum indication 0.001% Brix) is used for tea and unsweetened drinks.

Concentrations
The concentrations of industrial solutions are often monitored. Examples include water-based cutting oils and cleaning solutions, hydrogen peroxide, coolants, and alcohol solutions. Although the Brix scale is commonly used, user scales can also be programmed to display converted sample values.
