Hach-Lange ORBISPHERE 31xxx Thermal Basic User Manual - Manual (Page 7)

Electrical equipment marked with this symbol may not be disposed of in European public disposal
systems. In conformity with European local and national regulations, European electrical equipment
users must now return old or end-of-life equipment to the manufacturer for disposal at no charge to
the user.
Note: For return for recycling, please contact the equipment producer or supplier for instructions on how to return
end-of-life equipment, producer-supplied electrical accessories, and all auxillary items for proper disposal.
Products marked with this symbol indicates that the product contains toxic or hazardous substances
or elements. The number inside the symbol indicates the environmental protection use period in
years.
What you have received
Check that all mounting hardware is included. Note that, unless the sensor is part of ORBISPHERE
equipment that includes it, the sensor must be installed in an ORBISPHERE socket or flow chamber
that allows contact with the sample flow to be analyzed (refer to
Installation on page 8 for details).

The sensor head is protected by a screw-on plastic storage cap. The sensor may have an additional
in-line temperature sensor adapter (No. 6 in
Figure 2 ) that allows you to install a temperature sensor
directly into the sample flow.
The sensor has been carefully checked and calibrated in a production environment and following our
quality control procedures. As such, there is no need for any sensor maintenance or a change of
membrane, prior to installation. An easily removed label is stuck on the protection cap to remind you
of this.
Two small identification clips (stamped with the letter “T”) will be delivered with every sensor. They
should be used to identify the connection cable between the sensor and a multi-channel analyzer.
This is important in order to avoid connecting the sensor to the wrong measurement board.
Connecting a TC sensor to an EC measurement board (and vice versa) can damage both the sensor
and the electronics.
