The ATMOS is designed specifically for the agricultural and scientific markets. Wind speed, temperature, and relative humidity are measured. Windchill and dew point are calculated on the ATMOS. This unit is by far the best device for measuring windspeed, temperature, and humidity. It is simple to use, accurate, and dependable. The hygrometer never needs calibration, maintaining its high accuracy over the life of the product. Our SKYWATCH omni-directional windmeters have been used around the world in agriculture, marine, and outdoor markets for over a decade. Made in Switzerland with Swiss components, our customers have had many years of use from their instruments. This unit measures
Windspeed
Maximum windspeed

Details:

WINDSPEED:
Balanced impeller allows for wind measurement from any direction
The impeller is magnetized, producing a magnetic field when rotating which is measured internally

TEMPERATURE:
External thermometer is located under wind cups
Temperature adjusts quickly

RELATIVE HUMIDITY:
Relative humidity is dependant on measured temperature; allow device to adjust to temperature for accuracy
Relative humidity can change drastically over short areas, due to uneven humidity levels
The SKYWATCH Atmos features a hygrometer that does not need periodic calibration, for continuous accurate results
