Overview of equipment
Thank you very much for purchasing the HU-200TB SS-120 industrial-use turbidity meter.
This turbidity meter consists of a HU-200TB converter and a SS-120 distribution type turbidity
detector. This turbidity meter can measure a wide range of turbidities from low concentration
to high concentration with high accuracy through the 90-degree light absorption-scattering
method. Standard substances of turbidity are selectable from among Formazin, Kaolin, and
Polystyrene Latex (PSL).
The SS-120 detector for the HU-200TB SS-120 industrial-use turbidity meter can measure a
turbidity with high stability because the fluctuations in light intensity and the changes in
sensitivity of the detector are eliminated by using two LED light sources (660 nm) and two
photo detectors.
With its enhanced self-diagnosis capabilities, the status of this equipment is diagnosed at all
times.
The automatic cleaner (optional) for the SS-120 detector automatically cleans the dirt on the
inner surface of the cell which interfere with measurement. The operations such as the data
transfer of turbidity measurements and cleaning directives are carried out through
communications among the converter, the turbidity detector and the automatic cleaner. The
exclusive-use cable contains 5 wires for the 12 V DC power source, two-line communications,
and grounding.
If an automatic cleaner is installed, the length of the cable leading to the converter is 5 m. If an
automatic cleaner is not used, the cable can be extended up to 50 m.
Optional products offered by HORIBA Advanced Techno: the span calibration unit that can be
used in place of a standard solution at the time of span calibration; the piping unit that is used
to combine standard type pipes; and the filter unit that is used to prepare zero water.
