Hach Orbisphere C1100 Allgemeines Benutzerhandbuch Seite 7

The tube of the cell fits over the sensor head with the rubber O-ring inside the tube acting as a seal.
Most of the interior of the tube is lined with a concentric tube of black carbon to act as a counter
electrode during the cleaning process.
Figure 3 Regeneration cell for GA2x00 or C1100 sensors
Use the DG33619 regeneration cell to clean GA2x00 or C1100 sensors. Refer to
the blue banana plug into the counter electrode socket on the sensor cleaning and regeneration
center.
Note: Screw the DG33619 regeneration cell on the EC sensor.
Screw the regeneration cell on the sensor head with the rubber O-ring into the external groove acting
as a seal. An electrode into the cell acts as a counter electrode during the cleaning process.

Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
Chemical exposure hazard. The electrolyte is corrosive and can burn the eyes and skin. Obey
laboratory safety procedures and wear all of the personal protective equipment appropriate to the
chemicals that are handled. Refer to the current safety data sheets (MSDS/SDS) for safety protocols.
The Orbisphere DG33620 EC cleaning sensor support can hold two EC sensors during the cleaning
procedure. Refer to Figure
1. Remove the membrane and electrolyte from the sensor. Refer to the operator manual delivered
with the sensor for details on how to do this as the procedure is different depending on the type of
sensor.
2. Fix the sensor vertically onto a clamp or stand, so that its head is facing upwards. If the sensor
has a permanently attached cable, introduce the LEMO plug into the sensor receptacle (No. 6 in
Figure 1 on page 6). Sensors with detachable cables may connect directly to the sensor cable
(No. 3).
3. For the 29037 regeneration cell, push the tube of the regeneration cell over the sensor head until
it reaches a stop. Connect the red banana plug into the counter electrode socket (No. 7).
4. For the DG33619 regeneration cell, screw the regeneration cell in the sensor head. Connect the
blue banana plug into the counter electrode socket (No. 7).
