Many foods and drugs have to be stored within a specific cold temperature range. This can be done in individual cooled store rooms, but also in specialised cold stores or cold warehouses with high-rack facilities.
The temperature must be continuously documented in all these cold storage facilities, because strict rules apply to quality management in both the food and drugs industries.
Data loggers are usually installed at the so-called critical control points (CCPs) of the cold room, in order to identify any possible temperature deviations and to introduce appropriate countermeasures. Critical points are for instance doors or passages through to other temperature areas within a warehouse.
