Humidity - Wireless Outside

  • 2.4 GHz ZigBee™ wireless for easy installation
  • 2% or 3% accuracy (NIST certification options)
  • Field replaceable element

Applications

  • Outdoor humidity and temperature measurement for building control
  • Eliminate costly conduit runs and relocation

Description

The WO outside air series consists of a labor saving solar powered wireless temp/humidity transmitter with a remote receiver. This eliminates costly conduit, roof penetrations, and allows for easy repositioning should conditions warrant. Excellent stability with reliable operation.
