The pH/Temperature probe itself does not require traditional "calibration" like an instrument. Instead, the meter it connects to should be calibrated frequently (often daily or before each set of measurements) using standard pH buffer solutions. The temperature sensor can be verified or checked for accuracy periodically, typically annually or according to laboratory SOPs.
