Selection, compatibility and ordering notes
TopicTechnical note
Sample matrixConfirm whether sample alkalinity, ionic strength, contamination risk and temperature are appropriate for this electrode.
Connector matchingSpecified connector is S7. Confirm cable and meter input before ordering.
BNC(Q9) metersFor pH meters with BNC(Q9) input, use a correct S7-to-BNC(Q9) cable if applicable.
Temperature compensationIf the pH meter requires automatic temperature compensation, use a separate temperature probe unless the method uses manual temperature correction.
StorageStore according to laboratory pH electrode practice and avoid drying the sensing bulb and junction.
CalibrationCalibrate with suitable pH buffer solutions before measurement according to the laboratory method.
MaintenanceRinse after use, avoid mechanical shock to the glass bulb and follow cleaning procedure matched to the sample matrix.

📌 Practical Selection and Use Notes
For alkaline samples
Use case: select this electrode where the alkali-resistant product identity is relevant to the measurement task.
Confirmation: confirm sample chemistry before using any pH electrode in aggressive or unusual matrices.
For routine laboratory pH
Calibration: use fresh buffer solutions and follow the laboratory calibration procedure.
Handling: rinse between samples and avoid touching or mechanically damaging the glass sensing bulb.
For meter matching
Connector: confirm S7 connection and required cable before ordering.
ATC: use a separate temperature probe if the meter workflow requires automatic temperature compensation.
