| Technical Data |
| Measuring System: |
Optical-refraction critical-angle detection system |
| Constant-Temperature Function: |
Built-in thermo-module |
| Measurement Items: |
Refractive index(nD), Brix (Automatic temperature compensation) |
| User scale (30 kinds of user scale can be input) |
| Measurement Range: |
Refractive index (nD) 1.3250 to 1.7000; Brix 0.0 to 100.0% |
| Minimum Indication: |
Refractive index (nD): 0.0001/0.00001 by selection |
| Brix 0.1%/0.01% by selection |
| Temperature: 0.01°C |
| Measurement Accuracy: |
Brix: ±0.1% (on measurement of sucrose solution) |
| Refractive index (nD): ±0.0001 |
| Types of Modes: |
MODE1: |
The thermo-module in RX-7000a operates. If droplets of a sample are applied to the prism and then the start key is pressed, the measurement starts after the sample reaches the target temperature. |
| MODE2: |
The thermo-module in RX-7000a operates. If droplets of a sample are applied to the prism and then the start key is pressed, the unit measures the refractive index and temperature at a fixed interval and displays the estimated value at the target temperature. |
| MODE3: |
The user can turn on and off the thermo-module in RX-7000a freely. The unit starts measurement immediately after droplets of a sample are applied to the prism and the start switch is pressed, and displays the measured value 4 seconds later. The time to start measurement after the start key is pressed can be delayed manually. |
| Measurement Temperature: |
5.00 to 70.00°C (The lower limit is the room temperature minus 10°C) |
| Automatic Temperature Compensation Range for Brix: |
5.00 to 70.00°C |
| Temperature Display Accuracy: |
±0.05°C |
| Display Method: |
LCD display (320 x 240 dpi) with back light |
| Graphic Display: |
If top and bottom limits of standard value are set, top and bottom limit bar is displayed together with measured value. |
| Input of User Scale: |
If 3 points of a user scale corresponding to the refractive index are inputted, a conversion formula is automatically created |
| History Function: |
Up to 30 latest measurements can be displayed and can be printed |
| Zero Adjustment: |
Zero point is adjusted with distilled water |
| Manual Calibration: |
Indicated value can be changed in a certain range |

| Conditions for Temp Control (Temperature Range) : |
Ambient Temperature 15° (Temp. control can be set at 15 to 20°)
Ambient Temperature 20° (Temp. control can be set at 15 to 25°)
Ambient Temperature 25° (Temp. control can be set at 20 to 25°)
Ambient Temperature 30° (Temp. control can be set at 25°) |
| Measurement Modes: |
MODE1: |
This is the standard and most accurate mode of measurement. The sample’s temperature is adjusted to a set target temperature before measurement is taken. |
| MODE2: |
In this mode, the unit starts measuring immediately after 20 seconds. This time delay can be manually adjusted. In this mode, the thermo-module can be switched on or off freely. |
| Printer Interface: |
Centronics exclusively for Digital Printers DP-RX (thermal Output Terminals dot matrix) and DP-RD (impact dot matrix)(optional) PC interface: RX-232C - D-sub 9 connector |
