When is a good time to have a logger re-calibrated?

This question will cross the minds of everyone responsible for managing an inventory of loggers. Although not mandatory, it is good practice to have all loggers under your control re-calibrated on an annual basis, providing confidence in the accuracy and, therefore, peace of mind. Once every twelve months is a standard time period between calibrations. The calibration for our Scientific/Medical logger is valid for 24 months but we do recommend validation during that time. Following this voluntary schedule should be even more of a priority, especially when loggers are used to monitor the temperatures of medical-related processes or the storage conditions of high-value perishable products. The most common reason for a logger to go out of calibration is unintentional handling mishaps to a logger. i.e. any handling incidents suffered by a logger that are out of your control. For instance, while a logger is in transit with a product shipment etc.

As an example, if a logger has been dropped on the floor there is a chance that the temperature sensor has had stress applied to it from the fall. If this happens, the stress applied to the logger temperature sensor will change the characteristics of the temperature sensor, which can alter the accuracy of the logger. This event may shift the logger accuracy away from the results provided on the original calibration certificate. For this reason alone, it is good practice to have your loggers’ accuracy checked annually by re-calibration.
