Installation
3.1 Sensor installation
The electrochemical (EC) sensor connects to the instrument base through a 10-pin LEMO
connector. A locking nut holds the sensor in place. Generally, the sensor is shipped already
installed in the instrument. If this is not the case, for full installation instructions, please refer to
the Sensor Manual provided with your instrument.
3.2 Flow chamber installation
The model 32007E flow chamber draws the liquid or gaseous sample past the EC sensor. It
attaches to the sensor with a threaded collar and is then sealed to the sensor with two O-rings.
The flow chamber's centrally located inlet and eccentrically located outlet use either ¼-inch or
6-mm diameter transparent plastic tubing. Connect by compression fittings to the sample source
and to the drain, respectively.
You may also have received a model 32051 sample tube adapter to attach the flow chamber
inlet tubing to the sampling point (Refer to
