4.1 Sensor preparation

Your C1100 electrochemical sensor has been thoroughly cleaned and tested at the factory
before shipment. It has been shipped with a cartridge containing a membrane and electrolyte
pre-installed to protect the sensor head. This cartridge must be removed and replaced with a
new one prior to first use to make it fully operational. The new cartridge is included in the sensor
recharge kit (see additional details in
the mesh patches included with the kit.
The following instructions detail the steps required to make the sensor operational. Should you
have any questions, your Hach Lange representative will be pleased to help.
CAUTION
Avoid all eye and skin contact with the electrolyte in the sensor and replacement
cartridge. If eyes or skin come into contact with electrolyte, rinse immediately with water.
In addition, the electrolyte can permanently stain clothing so exercise care in handling. It
is highly recommended to wear protective gloves and glasses during this process.
Note: It is advisable to perform this procedure with the plastic sensor base installed so as to avoid any
damage to the connection socket and also to provide a suitable stand for the sensor when required.
