Measuring Principle
Turbidity Checker TSC-10-D uses a method of 90 degrees scattered light. In
the method, a light source of a sensor illuminates the surfaces of suspend-
ed matter floating in the water, and the light is scattered by these surfaces
is detected by a photo element installed at an angle of 90 degrees from the
light source. The turbidity is determined by the amount of scattered light.

Caution
Turbidity Checker uses a method of scattered light to
measure amount of reflected light. Therefore, measurement
values may be affected by measurement light reflected from
equipment surfaces or accumulated materials if the sensor is
installed nearby. Install the sensor with a clearance of at least
30 cm from the sensor surface to equipment or other surfaces.
If it is close, the measurement light hits and
the reflected light affects the measurement value.
Allow clearance of
at least 30 cm.
