• Adopt photoelectric detection and microcomputer control technology, large screen backlight LCD display, clear and intuitive data.
• Use light-emitting diodes and filters instead of sodium lamps; the instrument can be used without preheating when it is turned on.
• It can test the optical rotation, specific rotation, concentration and sugar content of the sample, and can automatically repeat the test 6 times and calculate the average value and root mean square.
• The sample tank is designed with temperature insulation, which reduces the influence of the temperature of the instrument on the sample test, and has a temperature display function, which is convenient for users.
• Can measure dark samples.
