Panametrics Systems I Hygrometer Panel Face w/ Housing # 1E-221-111-100-111 Got this from a government lab. Do not know much about these. Other models sell for lots. This is a hard to find model. I do know that this is missing all the cards and the lock mechanism. YOu are bascially buying the frame/housing and the panel interface. No back to this as well. But I will try to answer your questions the best I can.... Will ship international.
