​Accurate outdoor measurements are essential for building operations such as free cooling, cooling towers, and highly intelligent building automation systems. Changing weather can make measuring outdoor environmental conditions a challenge.

Vaisala’s outdoor transmitter portfolio includes products for measuring various humidity parameters (relative humidity, dew point, wet bulb, enthalpy, mixing ratio), temperature, wind, precipitation, carbon dioxide and barometric pressure. Outdoor transmitters come with wide operating temperature ranges suitable for most climates, flexible installation options, and solar and radiation shields for protection from the elements.
