TRH-100 Temperature & RH Probe
Uses two 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.
Connect up to two (2) Temperature / RH Probes to the XR440 Data Logger
Connect up to four (4) Temperature / RH Probes to the XR5-SE Data Logger
