A precision relative humidity and temperature probe which connects directly to the XR440 Data Logger, no external power required. Uses two XR440 input channels, one for temperature (dry bulb) and one for %RH, Wet Bulb, or Dew Point (software selectable). May also be used with other data acquisition systems, see electrical specifications for details.
