WeatherHawk 89499 ET Weather Station, Wireless

WeatherHawk ET Weather Station, Wireless

The wireless model features on-board 916 MHz spread spectrum radio communications for transmitting to a remote PC/Mac up to 1/2 mile line of sight.

Designed for easy installation and use! This industrial grade, fully assembled weather station measures wind speed and direction, air temperature, relative humidity, barometric pressure, solar radiation, rainfall, and ETo (evapotranspiration). The included WeatherHawk XP/X software allows for sophisticated data management and operates on PC-XP or Macintosh OS-X. Weather station, solar panel kit (for use in lieu of a DC power supply), and software included with both models.
