Features:

  • Independent Temperature and Relative Humidity Outputs.
  • %RH Accurate to 1.0%.
  • Temperature Accurate to 0.1%.
  • Low Cost.
  • Easy to Install.
  • Typically used with our WDT-DW wet and dry bulb humidity tank.

Optional: The IN-HWD will connect to our MicroScan SCADA software on the RS485 Modbus comms
(requires the PLC Modbus driver for direct connection to MicroScan; otherwise connect via a Intech Micro I/O Remote Station) for logging of the humidity and temperature.
