optical The QuadbeamTM Altenating Light Principle design is to improve the measurement reliability of the optical suspended solid and turbidity instrument. Sensor that use QuadbeamTM technology compensate for most sources of measurement erroe, providing unrivalled accuracy and reliability when compared with competative System.
The most basic method of suspended solid measurement is obtain by shining a light of know intensity a fixed distance through a medium to a photocell detector .
