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 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.
