Electrode Assembly And Preparation

The electrode is shipped assembled, with a membrane in place for packing. Disassemble the electrode as shown in step 1 of Figure 1, and discard the membrane. Reassemble according to instructions in Figure 1. After assembly the membrane should be slightly distended by the inner body of the electrode. A membrane should last several months, depending on usage. Membrane failure is characterized by a shift in electrode potential, drift, and poor response.

1. Remove top cap. Lift out inner body. Pour out old internal filling solution. Remove bottom cap.
2. Remove O-ring, old membrane and white spacer ring from cap.
3. Place the white membrane spacer ring in the bottom cap with the flat membrane down towards the sample solution.
4. Place O-ring on top of the white membrane spacer ring. Screw body into bottom cap.
5. Fill outer body with internal filling solution. Fill with about one inch of solution
6. Put inner body into outer body. Screw top cap on. Excess solutionwill vent.
