2 Information about this product
2.1 Product description
The measuring board of the TARAsys MT10-CL product line is suitable
for measuring chlorine dissolved in water and used as a disinfectant. The
areas of application are reverse osmosis systems and drinking water
applications.
In combination with the TARAline CP4.0H-M4c sensor, the measuring
board is suitable for verifying the absence of chlorine or for continuous
measurement of lowest chlorine concentrations.
Permanent operation in chlorine-free water is made possible through the
use of a miniaturised electrolysis cell specially designed to keep the
sensor free from biofilms in the phases without chlorine. For this purpose,
the disinfectant generated by the electrolysis cell is applied to the sensor
on a daily basis. This happens automatically through the closing of a
solenoid valve which stops the flow of the measuring water and thus
allows the diffusion of the disinfectant generated from the electrolysis cell
to the sensor.
A major advantage of this type is that no disinfectant has to be present in
the measuring water and thus the dosage of the disinfectant is not
necessary either.
The measuring board has been designed for the use of sensors with
retaining ring (65 mm).
Please specify when ordering your sensor.
In general, a complete measuring and control system is comprised of the
following components:
Sensor
Electrolysis cell
Measuring board
Dosing device
Analysis instruments

These Operating Instructions exclusively refer to the measuring
board equipped with the electrolysis cell.
Comply with the operating instructions of the peripheral devices.
2.1.1 Measurand
In combination with the TARAline CP4.0H-M4c sensor, the measuring
board measures the concentration of total chlorine in the measuring
water, i.e. the concentration resulting from the addition of inorganic
chlorine products (e.g. chlorine gas, sodium hypochlorite solution,
calcium hypochlorite solution.
The following kinds of chlorine are recorded:
“Free chlorine” from inorganic chlorination products (chlorine gas,
hypochlorite, etc.)
“Bound chlorine”, chloramine.
2.2 Scope of supply
Keep the complete packaging.
Send in the measuring board in its original packaging if it needs to be
repaired or in case of claims on warranty.
Check the package and its contents for completeness and integrity
upon receipt.
In case of damage:
Notify the supplier.
