Dual relative humidity and temperature transmitter for HVAC applications, environmental monitoring, pharmaceutical storage, food transport, greenhouse automation, etc. Equipped with an IP65 stainless steel AISI 304 housing, it is suitable even for severe environments; besides that, its ultra-compact dimensions (Ø14x138 mm or Ø14x155 mm depending on the models) and wide range of outputs (analogue 0…1V, digital RS232C or RS485-MODBUS RTU) make it ideal for integrating into a variety of OEM applications. It is supplied with the HD9817TC software for reading measurements and calibrating the relative humidity sensor.
