Installation

2.1 Storing the sensor
• Emerson recommends storing pH/ORP sensors in their original
shipping containers until needed.
• Store sensors in a temperature-controlled environment.
• If the sensor must be stored after it has been removed from
its shipping container, store the sensor tip downward with the
protective cap in place and containing KCL solution (PN 9210342).
• For overnight storage, immerse the sensor in tap water or a 4 pH
buffer solution.
• pH glass electrodes slowly deteriorate in storage. There is no
specific expiration date. Follow the calibration procedures in
Calibration and maintenance
properly.
2.2 Prepare sensor
Procedure
1. Remove sensor from shipping container
2. Remove the protective cap covering the electrode bulb.
3. Rinse away salt film with clean water; then shake the electrode

trapped there.
