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
Output: 1. Digital Printer DP-62a (Optional)
2. Communication method: RS-232C
Input Power Source: AC100 to 240V, 50/60Hz
