Cold chain monitoring (EN12830) is crucial for industries like healthcare, food industry processing, paints, etc. For such industries temperature and humidity, variations determine the success of the treatment, quality of food, paint, print, etc. For example, in meat processing, there are chances of freeze damage if the meat is stored at a warmer temperature than -1.5 degrees celsius. It is ideal that the cold storage maintains a temperature close to -1.5 degrees celsius.
Some of these are based on European standards (EN12830) Though there are devices that can track temperature and humidity the human interventions required increases the chance for errors and contamination. Moreover, immediate action has to be taken to curb the extent of damage caused.
