1.1 Symbols and displays
1.1.1 Safety and warning instructions
The hazard symbols and signal words listed below are used in these
operating instructions. They help you use the product safely, protect the
operating personnel against injuries and protect the operating company
against damage to property and additional costs.
Signal word Meaning
DANGER! DANGER means a hazard with a high degree
of risk which if not avoided will lead to death or
serious injury.
WARNING! WARNING means a hazard with a medium
degree of risk which if not avoided may lead to
death or serious injury.
CAUTION! CAUTION means a hazard with a low degree of
risk which if not avoided may lead to minor or
moderate injury.
NOTE NOTE warns against damage to property.

2 Information on this product
2.1 Product description
The TARAtec 9/10 product range consists of sensors with covering
membranes.
They are 2-electrode systems for measuring the concentrations in water
of the disinfectants chlorine1, peracetic acid or hydrogen peroxide. In
comparison to the product range TARAtec 7 the TARAtec 9/10 sensors
are characterised by improved resistance to media for reducing surface
tension (tensides). In addition, TARAtec 9 sensors can be used when the
water being measured is at high temperatures. The area of application of
these sensors extends to almost all water qualities.
The sensors are not suitable for checking the absence of chlorine,
peracetic acid or hydrogen peroxide.
A complete measuring and/or control system normally consists of the
following components:
Sensor
Electrical leads and connectors
Flow chambers and connections
Measuring and control device
Dosing equipment
Analytical equipment
These operating instructions relate exclusively to the sensor.
Comply with the operating instructions for the peripheral
devices.
1Free chlorine (dependent on the pH value)

Information on this product
TARAtec 9/10 7 / 44
2.1.1 Peracetic acid P9 and P10
The sensor measures the concentration of peracetic acid in the water
being measured resulting from the application of peracetic acid.
2.1.2 Hydrogen peroxide WP10
The sensor measures the concentration of hydrogen peroxide in the
water being measured resulting from the application of hydrogen
peroxide.
2.1.3 Chlorine CH10
The sensor measures the concentration of free chlorine in the water
being measured. Such chlorine arises from the application of inorganic
chlorine products (such as chlorine gas, sodium hypochlorite solution,
calcium hypochlorite solution).
The sensor can be used in the pH range from pH 5.0 to pH 8.0. It is
essential to keep the pH value at a constant level, since the sensor signal
tracks the dissociation curve of the hypochlorous acid. The sensor shows
different chlorine values different values depending on the pH value
although no change in the chlorine concentration can be recognised in
the DPD-1 measuring values or iodometric measuring values.
When organic chlorine products or chlorine stabilisers are used, both
based on (iso) cyanuric acid as a rule, there may be considerable
differences between the DPD-1 measuring value or iodometric measuring
value and the signal of the chlorine sensor.
