The RX-5000α (ALPHA) Digital Refractometer has an internal heating/cooling mechanism, providing the ultimate in digital accuracy and precision for the Refractive Index (nD) and Brix testing of dissolved solids.
Easy to Use
Operation consists of placing a sample on the prism, pressing the START button and in a few seconds the result is displayed on the large LCD screen. The unit automatically calibrates with distilled water.
High Precision
Featuring wide ranges and high resolution / accuracy for both Refractive Index (nD) and Brix, the RX-5000a offers the highest level of precision available in a digital refractometer.
Digital Accuracy
The LCD digital display and push-button operation both enhance overall precision - no dials to turn, no analog scales to read.
Flow Cell Attachment.
This attachment allows customers to pour the sample onto the prism surface, take a measurement and then flush the flow cell with water. Then they can take their next measurement. The operator will no longer have to wipe the prism surface after every measurement.
Internal Heating/Cooling Mechanism
Featuring Peltier technology, the internal heating/cooling mechanism completely eliminates the need for an external constant temperature bath. Any temperature value between 5-60°C can be entered as the target temperature. After the START button is pressed, The RX-5000a displays the reading when the prism and sample are heated or cooled to the target temperature (MODE 1). Note: The RX-5000a has two additional modes: MODE 2 displays readings based on a calculation of the target temperature entered; MODE 3 switches the internal heating/cooling mechanism off entirely, with readings based on the current temperature of the prism.
Professional Features
Large, menu-driven LCD display; push-button operation; contrast setting for the display; wait-time setting (0-99 seconds); measurement history (last 30 readings); centronics printer port (parallel); RS-232C computer port (serial); built-in clock displaying date and time.
User-Defined Tolerance Levels
Allows users to quickly monitor the readings of samples by individually setting upper and lower limits for the Brix, Refractive Index (nD), and the 60 user scales. Whether sample readings remain in or fall out of the specified tolerance, the results are digitally represented through the use of a horizontal bar graph on the LCD display.
Programmable User Scales
60 programmable user scales are available for the custom concentration levels of specific solutions. Scales are easily entered manually with the use of the keypad & LCD display. A backup battery stores the scales and any other custom information. Note: 3 points of actual measurement data, corresponding to refractive index (nD), are required for each custom scale. Upon completion of data entry, the RX-5000a automatically calculates the scale for immediate use. Scale units available: %,g/100g, g/100ml, mol/l, %mas, & %vol.
LED Light Source
The long-lasting LED light source with a 589.3nm (Sodium D-line) interference filter is intended to last the life of the instrument.
Automatic Temperature Compensation
Features Automatic Temperature Compensation for the Brix scale with 20°C as the reference temperature. The effective compensation range for the Brix scale is 5-60°C.
Features
Automatic measurement at your targeted temperature
Measurements can be started without worrying about current temperature.
Brix and the refractive index at your targeted temperature are quickly displayed.
Constant temperature water bath is not necessary
Since the RX-5000a has a thermo-module to control temperature, the measurement starts after the sample reaches your targeted temperature.
Raising and lowering of the temperature are possible in a short time.
High Accuracy with the latest technology
High Brix ±0.03% and refractive index ±0.00004 accuracy can be obtained.
Up to 60 kinds of user scales are made by this machine.
Sixty kinds of user scales can be input according to your sample. If 3 points of actual measurement
data corresponding to the refractive index are input, the RX-5000a makes your customized scale
automatically.
Flow Cell Attachment.
This attachment allows customers to pour the sample onto the prism surface, take a measurement and then flush the flow cell with water. Then they can take their next measurement. The operator will no longer have to wipe the prism surface after every measurement.
History function
The RX-5000a is capable of calling up 30 latest measurements.
With an optional DP-62a Digital Printer, measurement data can be printed out.
New user-friendly function
The RX-5000a displays the top-and-bottom-limit-bar for your set control range (tolerance).
You can see at a glance whether the measured value is within the tolerance.
Printing of Contents
Name of sample, as well as the number of samples, date, month, year, time, measurement value and temperature can also be printed out.
