Applications
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.
Temperature monitoring in deep-freeze rooms for foods
There are a huge number of facilities where (deep-)frozen food has to be stored. These range from individual deep-freeze rooms on small food producers’ sites (e.g. butchers), at restaurants and supermarkets, via deep-freeze rooms in the food industry, through to specialized cold stores / deep-freeze warehouses with high-rack facilities. The temperature must be continuously documented in all these facilities. In Europe, only temperature loggers may be used in this process which are approved according to EN 12830.
Typically, data loggers are used to measure the air temperature in storage facilities of this kind. The measuring instrument is installed in the deep-freeze room ? as far as possible at critical points such as doors or cooling plants ? and records the temperature data at defined intervals (typically: 15 minutes).
The recorded data can then be analyzed and archived using special software.
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, analyzed and archived by means of special software.
