9.2 Turbidity

The lifetime of the Turbidity Sensor is mainly limited by the light source. The lifetime of
the light source is around 5 years. It is possible to change the light source by loosening the
endcap of the Emitter. Make sure not to touch the new light bulb and to secure the
connector firmly. It is also possible to change the entire Emitter as well as the Receiver
and the Wiper Unit. The wires must be connected as shown on Figure 9-1.
The lifetime of the wiper blades is according to water quality. It must be replaced when
necessary.

9.3 pH/Temperature

The lifetime of the pH/temperature sensor is mainly limited by the lifetime of the electrode.
The electrode has a shelf life of 1 year at 25°C followed by an operating lifetime of
approximately 1 year at 25°C. Electrode lifetime will be shortened at elevated temperature,
elevated pressure and by pollution from the media. The electrode must always be kept
moist. If the electrode dries out, it will not operate properly. Please refer to electrode
trouble shooting section.
Changing of the Electrode is easily done by following the maintenance instruction
MI6100-0007.
Note
It is recommended to keep an electrode in stock as a spare part.
