The polarimeter is the basic scientific instrument used to measure angle of rotation, specific optical rotation of optically active substance.
The polarimeter built-in auto-controlling system. Power on the instrument, the system will search for zero point automatically. You need only put a sample tubes into the measuring field chamber, the polarimeter will displays a angle of rotation.
WZZ-2A can auto-judge levorotatory or dextrorotatory of compounds. If the reading is negative measured value,it means is that sample is levorotatory substance, if the reading is positive measured value, the sample is dextrorotatory substance.
During measurement, you need to test a sample solution 3 times or more to ensure its accuracy. Press + or key, the instrument will remeasure sample.
From angle of rotation by polarimeter, we can calculate purity, concentration, percentage of sample.
