The Polarimeter PDA 5000 is a photoelectric instrument with balancing controlled by a servo motor. The angular deviation (rotation) of a polarized light beam in a sample is measured by compensating for that angle, carried out by means of a rotary analyzer. The desevanalizador rotation, which is directly proportional to the deviation, is measured by means of an angular encoder that emits counting signals. These are totaled and after being electronically conditioned they provide the value and direction of the angular deviation of a digital indicator. The instruments automatically measure light (-) or dextrogenic (+) speeds. Additional electronic circuits compensate for the turbidity of the samples and signal the operator when the result is unreliable.
