Disassembly is normally not required or recommended. If
crystals or other matter are seen between outer body and
inner cone, the electrode may be disassembled for cleaning
or inspection. Protect the cone surface from oils or dirt by
using gloves or lab tissues.
1. Drain fill solution from electrode body by depressing
the upper cap while holding the outer body.
2. Rinse inner body with deionized water and drain by
pressing the upper cap.
3. Unscrew upper cap and slide cap and spring up the
sensor cable toward the connector.
4. Push the inner body through the outer sleeve by gently
pushing down on the inner body near the threads.
5. Grasp the cone and gently pull assembly out of sleeve.
6. Cone may be cleaned with deionized water and a soft
lab tissue (HI 731318).
7. Clean and inspect internal surface of outer body.
8. Reassemble electrode by gently pushing the inner
stem assembly into the outer body, sliding spring
down cable, and screwing cap into place. (Refer to
Section VI; Electrode Preparation).
9. Refill electrolyte, flush junction, and then top off
electrolyte.

Storage
The HI 5315 reference electrode may be stored in air or
aqueous solutions between sample measurements.
If the electrode will be used frequently and needs to be
ready for use, take measures to prevent evaporation of fill
solution. Top off fill solution, replace o-ring and fill hole
plug on the fill hole opening, and place protective cap over
junction tip. Store electrode upright. Before using, flush
junction once and top off fill solution.
For long term storage, disassemble electrode and wash all
salts from assembly with deionized water. Wrap ceramic
junction on inner stem with Parafilm
®
or other sealing
film. Store dry and disassembled.
