COLOUR/TURBIDITY MONITOR
COL-110
The COL-110 measures simultaneously measure two
parameters, color and turbidity in water, by a single light
path in different two wavelengths of the tranmitted light
measurement principle.
Features
Single unit for conducting color and turbidity analysis
The COL-110 can perform measurements at two
different wavelengths. This makes it possible to
conduct not only turbidity measurements, but also color
measurements for which turbidity has been corrected.
Easy reading & simple operation design
The real-time readouts of the color and turbidity
measurements appear simultaneously on the large
color display of the front panel. In addition to the
readouts, the display also shows measurement trends.
This particular feature is especially convenient for
analyzing the causes of errors and abnormalities.
The operation section consists of an easy-to-read
interactive touch panel, making the COL-110 incredibly
easy to use.
Long-term, stable, and reliable measurements
The COL-110 employs a unique debubbling method
that effectively prevents the formation of bubbles in the
measurement cell. In the event bubbles accidentally
form, they can be completely removed by washing.
These capabilities enable the unit to maintain stability
in measurements.
The COL-110 also performs automatic zero calibration
by injecting zero water into the measurement cell at
regular intervals. This helps to compensate for the
effect of dirt that collects on the cell window, thereby
ensuring the unit provides consistently accurate
measurements.
In addition, the COL-110 is equipped with an electronic
dehumidifier designed to prevent condensation from
forming inside the unit. Removing condensation
minimizes the impact of moisture on measurement
accuracy and prevents rust from accumulating inside,
which in turn further enhances the durability of the unit.
Internal data memory
One minute values can be stored in 3-month intervals,
and one hour values can be stored in 1-year intervals.
The optional memory card is convenient for storing and
transporting data.
