1 Storage cap

3 Purge gas inlet
The sensor head is protected by a screw-on plastic storage cap. The sensor can connect to an
optional in-line temperature sensor (No. 5 in
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.
4.2 A sensor maintenance kit
The maintenance kit includes the material needed to service and maintain the sensor.
Section 5 Storage information
During a short shutdown period (such as weekends), the sensor may stay in place with the
instrument turned on, and purge gas supplied. If the inactive period is likely to last longer, remove the
sensor, wipe it dry and store it properly, using the plastic storage cap supplied.
