Frequent Uses

Primary Calibration of pH Meters

Used as the central calibration point for pH electrodes, supporting single or multi-point calibration routines around neutral pH.

Routine Quality Control Checks

Ideal for daily verification of instrument performance and documenting traceability to NIST within GLP and ISO workflows.

Temperature Compensation Verification

Supports checks of automatic temperature compensation by confirming stable readings near 25°C and referencing known temperature–pH behaviour.

Rinsing Between Calibration Points

Used to rinse probes between buffer steps to minimise cross-contamination during multi-point calibration sequences.

Education and Training

Suitable for teaching labs and training sessions to demonstrate best practice in pH measurement and calibration.
