  • 8-inch long sensor that extends inside the duct to provide an accurate reading.
  • Set point from 30 to 100% R.H.
  • An ABS housing rated IP54 (equivalent to NEMA 3)
  • It can be used as a high limit duct humidistat in the supply duct or to control the humidity level in the space when it is installed in the return duct.
