5 Maintenance and changing the electrode
The NitraLyt
®
700 IQ nitrate sensor is maintenance-free.
Warning
Contact with the sample can be dangerous for the user! Depending on
the type of sample, suitable protective measures must be taken (pro-
tective clothing, protective goggles, etc.).
Note
To keep the sensor clean we absolutely recommend to use the CH
cleaning head (see chapter 6 R
EPLACEMENT PARTS AND ACCESSORIES
).
Note
Please read the maintenance of the combination electrode in the rele-
vant operating manual of the electrode.
Note
We do not recommend unscrewing the sensor from the sensor connec-
tion cable when changing the electrode. Otherwise, moisture and/or dirt
can get into the plug connection where it can cause contact problems.
If you need to disconnect the sensor from the sensor connection cable,
please note the following points:
!
Before disconnecting the sensor from the SACIQ sensor connection
cable, remove any larger pieces of contamination from the sensor,
particularly in the area of the plug connection (brush it off in a bucket
of tap water, wash it off with a hose or wipe it off with a cloth).
!
Unscrew the sensor from the SACIQ sensor connection cable.
!
Always place a protective cap on the plug head of the sensor and on
the SACIQ sensor connection cable so that no moisture or dirt can
get into the contacting surfaces.
