  • Page 117 9 Reference Data Measurement Principle The rotary cell length modulation method, which combines high performance and reliability, is adopted in this unit. Two cylinder cells are placed, arranged with the light source and detector in a position where they are decentered from the center of cylinder as shown in the figure below. By rotating these two cylinder cells with the centers of the light source and detector as the rotation center, the distance between the 2 cylinders (cell length) is modulated continuously and periodically.
  • Page 118 9 Reference Data TURB (turbidity) Measurement TURB measurement is performed by using the visible light (VIS) absorbance. The measurement method is the transmitting absorption method. Calibration with the standard solution enables a simple measurement of TURB. Measure in the measurement range of 200 or below. If measuring in a measurement range that exceeds the specified value, the linearity deteriorates due to the scattering light influence.
