More details


These humidity indicators provide a quick and inexpensive means of checking relative humidity levels of your storage or display areas. As humidity changes the chemically impregnated spots change from blue (dry) to pink (humid). The cards indicate the current humidity level and come with a pressure sensitive adhesive backing. Can also be used in a sealed frame package to monitor humidity levels in framed artwork.
