Selection, compatibility and ordering notes
| Topic | Technical note |
| Sample matrix | Confirm whether sample alkalinity, ionic strength, contamination risk and temperature are appropriate for this electrode. |
| Connector matching | Specified connector is S7. Confirm cable and meter input before ordering. |
| BNC(Q9) meters | For pH meters with BNC(Q9) input, use a correct S7-to-BNC(Q9) cable if applicable. |
| Temperature compensation | If the pH meter requires automatic temperature compensation, use a separate temperature probe unless the method uses manual temperature correction. |
| Storage | Store according to laboratory pH electrode practice and avoid drying the sensing bulb and junction. |
| Calibration | Calibrate with suitable pH buffer solutions before measurement according to the laboratory method. |
| Maintenance | Rinse after use, avoid mechanical shock to the glass bulb and follow cleaning procedure matched to the sample matrix. |
