There are many facilities where (deep) frozen foods need to be stored. These range from individual freezer rooms at small food manufacturers (e.g. butchers), restaurants and supermarkets, freezer rooms in the food processing industry, right through to specialised cold storage warehouses/high bay freezer warehouses. In all of these facilities, the temperature has to be documented continuously. In Europe, only temperature recording devices that comply with EN 12830 are allowed to be used.
Data loggers are typically used to measure the air temperature in these kinds of storage facilities. The measuring instrument is positioned within the freezer room at the critical places where possible, such as by doors or refrigeration units, where it records temperature data at specified intervals (typically: every 15 minutes).
With the aid of special software, the recorded data can consequently be analysed and stored.
