1.1 Sensor Installation
The sensor has a threaded collar and calibration cap, and a screw-on protection cap to prevent disturbances to the membrane. A plastic screw-on base at its rear provides a stand for servicing, and protects the sensor's screw-on 10-pin LEMO connection.

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 EC Sensors Maintenance & Installation Manual that was provided with your instrument.
Should a sensor service be required, then again please refer to the EC Sensors Maintenance & Installation Manual for instructions on sensor servicing.
1.2 Flow Chamber Installation
The model 32007F flow chamber (illustrated in Fig 1-3below) 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 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.
