Automatic Polarimeter (constant temperature)

Features:

The feature of AP-SGWZZ-2 automatic polarimeter is using luminous diode as light source, whose lifetime is more than 20,000 hours, instead of sodium lamp which is of low lifetime ,easily damaged, also instead of

halogen tungsten lamp of higher temperature. In this way it greatly eliminate inconvenience caused by changing sodium lamp frequently. There are four test modes, optical rotation, specific rotation, concentration, sugar degree, could automatically test 6 times repeatedly, and calculate average value and mean square root. could test dark sample. There are heat and cool function on AP-SGWZZ-2 Peltier device, there are also heat and cool function on temperature control function device. If using temperature-controlled type test tube, could control temperature and measure to sample optical rotation. Large screen liquid crystal display (LCD) provides man-machine dialog menu operation mode, simple and intuitive, stable and reliable. Instrument adopt large screen touch liquid crystal display (LCD).
