Cold storage monitoring and walk in freezer monitoring are required for various temperature sensitive items such as medicines, vaccines, fruits, vegetables, fresh food, frozen food etc. which are stored under temperature controlled rooms. The storage time can be from couple of days to couple of years depending on the usage. Hence these items should never exceed permitted temperature and the conditions need to be continuously monitored and recorded. As per regulatory requirements, it might be required to check the recorded data periodically to ensure that the items have been maintained under stipulated conditions. Also nowadays insurance companies insist to have continuous recording so that they can verify upon any claims for damaged goods.
