| SGW-1 Automatic Polarimeter |
Characteristics:
The sodium lamp was replaced by a light-emitting diode (LED) and a filter, and the average service life of the light source is no more than 5000 hours. This instrument needs not to be warmed up before startup. The optical rotation, specific rotation, concentration and sugar content of the samples 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. An insulation design was adopted for the sample well, so that the influence of temperature rise on the measurement may be reduced. There is a function for temperature display, which is convenient for the users. Samples of deep color may be measured too. |
Main technical parameters:
◆ Measuring range: -45° to 45°; -45°Z to 120°Z (sugar content)
◆ Minimum reading value: 0.001
◆ Accuracy: ±(0.05+ measured value * 0.03%); ±(0.015 Z+ measured value * 0.03%)
◆ Repeatability: (standard deviation): 0.002; 0.006 Z
◆ The lowest penetration rate of the measurable samples: 1%
◆ With USB interface |
