Be sure to read this instruction manual in order to
use this Turbidity Checker properly.
●Please thoroughly read "For Safe Use" before using this Turbidity
Checker properly.
●Because these precautions are related to failure or malfunction, observe
the precautions for use without fail.
Do not use TSC-10-D except for measurement of water
quality.
" " denotes "Prohibited action", and " " denotes "Required action" .
In the unlikely event of
occurrence of abnormalities
such as smoke or abnormal
noise, immediately turn off
the power.
Do not disassemble or
modify the sensor.
Handle with care not to
damage.
Use the sensor with
24 VDC.

To clean the sensor, first
wipe away lightly with a clean
soft cloth damped by diluted
mild detergent solution and
then wipe off moisture with
a dry clean soft cloth.
Do not wipe the sensor with
solvent such as Thinner.
It may cause failure.

3 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.
Photo elementLight source (LED)
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.

4 Installation
Before installation, turn off the power switch of SC-U1 or
disconnect the power cable from the supply source and wire
the power cable after the installation is complete.
" " denotes "Prohibited action", and " " denotes "Required action" .
When installing the sensor,
make sure that the sensor
is oriented relative to the
water flow as shown in the
illustration. Otherwise,
suspended matter in the
water will adhere to the
detection surface and affect
the measurement value.
Do not install the sensor with
the sensor surface facing
down. Bubbles may
accumulate in the
measurement area, or the
measurement light may be
reflected off the bottom of
the facility or accumulated
objects, making it impossible
to measure correctly.
Water flow
Do not install the sensor
near a wall or other
surface. Measurement light
will strike the surface and
the reflected light will affect
the measurement values.
Install the sensor avoiding
the situation that the
sensor surface receive
strong light such as
sunlight directly.

With fluctuation of water
level taken into account,
dispose the sensor so as
to be immersed up to of the
order of 30 cm below the
expected lowest water level.
Dispose the sensor in
water without air bubbles.
30 cm min.
(2 meter max.)
Reference
The sensor can be installed in landscape
orientation, and in order to prevent the
sensor from hitting the side wall or
rotating by the water flow, a mounting
attachment (TA-3) for fixing the sensor to
the pipe is available as an option.

*Pipe: The 25A stainless steel pipe (outer
diameter 34 mm) for piping to be
prepared by the user.
・Read the precautions in the “TA-3 instruction manual” carefully.
・Be sure to install the cable protective cover. Otherwise the cable may be
damaged and flooded during maintenance.
