Hi there, our company orders lots of medical supplies from venders that requires them to add in the temperature humidity monitor to keep track of temperatures. But once we received the item we no longer need them. Over the time we have collected tons of them. We are selling them for cheap, they are pretty new, just only used for this one time shipping supplies to us. They are all in working conditions and batteries are included. We are selling a (set of 6) for cheap price, thanks for looking.
