Operating instructions:
a) The electrode must be stored in 3 mol/l KCl (ours type: KCl3M), in order to avoid drying out (excluded GE103).
b) The electrodes must only be used with the suitable devices. Wen using inappropriate devices the electrode and
the device can be damaged or destructed!
c) Device and sensor must be treated well and must be used according to the given technical specification (do not
throw, bounce, etc...). Plug and sockets of the device and the electrode must be protected from contamination
and humidity.
d) Before measuring the protection-cap has to be removed.
e) Calibrating of the measuring cell (single-rod measuring cell or measuring- and reference-electrode) have to be
done according to the manufacturers instructions buffer-dilution with a value that is near the measuring cell (e.g.
pH 7,0) the “asymmetry” is set. For the slope (pH X) a second buffer-dilution is used which pH-Value should be
within the measuring range (e.g. pH 4,0; pH 10,0; pH12,0), but at least 2 pH-units different form the buffer-
dilution used first.
f) Our pH-electrodes can be used in a degree range from 90° to ±45° compared to horizontal
Disposal instructions
Exhausted pH-electrodes must be disposed via special refuse. When delivering exhausted electrodes from our
product range, free for us (sufficient post paid), we will dispose them for free.
Safety regulations
This device was designed and tested considering the safety regulations for electronic measuring devices.
Faultless operation and reliability in operation of the measuring device can only be assured if the General Safety
Measures and the devices specific safety regulation mentioned in this users manual are considered.
1. Faultless operation and reliability in operation of the measuring device can only be assured if the device is used
within the climatic conditions specified in the chapter “Specifications“.
2. When transporting the device from a cold to a warm environment, condensation could affect the device’s func-
tion. In this case you have to wait until the device has the same temperature as the environment before using it.
3. When connecting the device to other devices the interconnection has to be designed most thoroughly, as inter-
nal connections in third-party devices (e.g. connection of ground with protective earth) may lead to undesired
voltage potentials that can affect the connected devices, could damage them or even may destruct the devices.
4. The device must be switched off and must be marked against using again, in case of obvious malfunctions of
the device which are e.g.:
- visible damage.
- the device is not working as prescribed.
- storing the device under inappropriate conditions for longer time.
When not sure, the device should be sent to the manufacturer for repairing or servicing.
5. Attention: Do NOT use this product as safety or emergency stopping device, or in any other application where
failure of the product could result in personal injury or material damage.
Failure to comply with these instructions could result in death or serious injury and material damage.
6. The electrodes contain 3 molar KCL (GE103: 1mol/l KNO
3
), which is acidly.
First-Aid-provisions
After contact with skin: clean with sufficient water.
After contact with eyes: rinse opened eye with sufficient water, contact oculist
After swallowing: drink much water. When feeling sick, contact doctor.
7. Attention! The electrodes containing glass. If the ph-electrode is damaged please abolish the medium being
measured! If swallowed gullet and gastrointestinal tract could be injured.
