| WZZ-3 Automatic Polarimeter |
Characteristics:
With technology of photoelectric detection and micrcomputer control, as well as large-screen backlit LCD display, the data is visual and clear. The optical rotation, specific rotation, concentration and sugar content may be automatically measured (1 to 6 times dependent on your selection), and then the average as well as the root mean square (RMS) may be worked out automatically. There is a RS232 interface for sending the data to PC. |
Main technical parameters:
◆ Measuring range: -45° to 45°; -120° Z to 120° Z (sugar content)
◆ Minimum reading value : 0.001; 0.001 Z
◆ Accuracy: ± (0.01 + measured value * 0.05%); ± (0.03 Z + measured value * 0.05%)
◆ Repeatability: (Standard deviation): 0.003; 0.009 Z
◆ The lowest penetration rate for the measurable samples: 10% |
