A tool for mapping temperatures in various types of cold chain equipment and dry stores, available in official United Nations (UN) languages. Temperature mapping is the process of recording and mapping temperatures within three-dimensional (3D) spaces, such as cold and freezer rooms, dry storage areas, and refrigerator and freezer units. Temperature mapping and temperature monitoring are integral to the appropriate storage conditions for pharmaceuticals. Good manufacturing practice for pharmaceutical products recommends regular temperature mapping in all types of warehouses.
