The pr obe is dir ectly connected to the tr ansmitter,
making it easy to install without the need for
additional fixed joints. It is widely used in communication
rooms,warehouse buildings, archival and
cultural relics preservation, flower breeding, agricultural
greenhouses,cement curing rooms, underground
railway and tunnel engineering, papermaking,
textiles, tobacco, distribution cabinets, and
other scenarios that require temperature and
humidity me asurement.
