The NEW Model RX-5000 (ALPHA) Digital Refractometer, through the use of its internal heating/cooling mechanism, provides 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 water - a zero indicator lets the user know the unit is properly calibrated.


High precision
Featuring wide ranges and high resolution / accuracy for both Refractive Index (nD) and Brix, Model RX-5000 alfa 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.


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 5.00-60.00°C can be entered as the target temperature. After the START button is pressed, Model RX-5000 displays the reading when the prism and sample are heated or cooled to the target temperature (MODE 1).

Note: The RX-5000 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-define 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 30 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
30 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/1 00g, g/1 00ml, mol/l, %mas, & %vol.


Custom calibration
Model RX-5000 can also be calibrated manually at any 1 point with the use of a liquid standard or user-prepared standard.


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.

Note: The refractive index (nD) scale is not temperature compensated.
