Monitoring and documentation of the temperature in cold rooms

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.

Monitoring and documentation of transport temperature

For all goods which react sensitively to temperature fluctuations or have to be stored within a predefined temperature range, uninterrupted measurement data recording and documentation play a major role.
Incorrect temperature conditions during transport can lead to major losses of quality, including the total loss of value of the products that require monitoring.
Using a data logger, shipments can be checked for compliance with the specified temperature ranges and the data can then be read, analysed and archived by means of special software.

Monitoring the temperature in deep-freeze rooms for food

There are many facilities where (deep) frozen foods need to be stored. These range from individual deep-freeze rooms at small food producers (e.g. butcher’s shops), restaurants and supermarkets, via deep-freeze rooms in the food processing industry, right through to specialized refrigerated warehouses/high-bay deep-freeze warehouses. In all of these facilities, the temperature has to be documented continuously. Only temperature recording devices that comply with EN 12830 are allowed to be used in Europe.

Data loggers are typically used to measure the air temperature in storage facilities of this kind. The measuring instrument is positioned in the deep-freeze room, where possible at critical locations, such as doors or refrigeration units, where it records temperature data at specified intervals (typically: every 15 minutes). The recorded data can subsequently be analyzed and archived using special software.
