pH probes, including the InLab Expert Pro, should be calibrated regularly—ideally before each use or at least daily if used frequently. The actual interval can depend on the accuracy required, sample type, and manufacturer recommendations. Most laboratories calibrate at the start of each working day or before each series of measurements.
