The system for measuring free chlorine, chlorine dioxide or ozone is a ready to use and tested
measuring system with integrated temperature sensor for compensation. As an option a pH
measurement can be added as well as the Automatic Sensor Cleaning (ASR, Patent Dr. A.
Kuntze). The sensors have to be installed and calibrated before use.

2 DEVICE DESCRIPTION
2.3 Device description of the sensor
The sensor for measuring free chlorine, chlorine dioxide or ozone is characterised by a robust
design and extremely low maintenance requirements. The sensor comprise double gold
electrodes and a low maintenance gel filling. The sensor measurement is virtually flow
independent above 30 l/h / 7.93 gal/h, the optimum is a stable flow between 50...150 l/h /
13.21...39.63 gal/h.

5 Reference electrode
The sensor is equipped with the patented Automatic Sensor Cleaning (ASR, Patent Dr. A.
Kuntze). An electrochemical process causes outgassing on the gold electrodes, dissolving even
tough coatings such as lime deposits. The ASR considerably increases the life span of the
sensors, achieving high measuring stability with extremely low maintenance requirements.
2.4 Nameplate
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
The system type is specified on the labelling of the measuring system package and on the
measuring system itself.

3 INSTALLATION
3.3 Installing the sensor
3.3.1 Mounting to OPTISYS CL 1100 measuring system
The measuring system is delivered ready-to-use. It can be mounted in a distance of 20 mm /
0.79" to a wall via 4 predrilled holes.
Water connection
Connect the water inlet on the left side and the outlet on the right side of the flow cell. The outlet
can be an open outlet (pressureless) or the water can be re-directed into a pipe or basin.
CAUTION!
Install the device at a place where mechanical and chemical stress is limited.
Mind the ingress ptotection: IP 65 (with closed terminal cover)
CAUTION!
The sensors are delivered with protective caps, which have to be removed before mounting into
the flow cell.

4 Terminal block Pos.B: terminal for pH sensor and temperature
The sensors for free chlorine, chlorine dioxide or ozone are always connected to terminal block
Pos.A of the signal converter. Depending on the configuration of the signal converter, a pH
sensor may be connected to terminal block Pos.B. An external temperature sensor may be
connected to terminal block Pos.A. (For detailed information how to install and configure a pH
and/or a temperature sensor please refer to the pH sensor documentation.)
