WS501 Ultrasonic weather station with solar pyranometer

air temperature / relative humidity / air pressure / wind speed / wind direction / solar radiation

From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications.

Integrated design with ventilated radiation protection for measuring:

• Air temperature
• Relative humidity
• Air pressure
• Wind direction
• Wind speed
• Solar Radiation

Available with low-power setting for remote stations with solar power.

Measurement output can be accessed by the following protocols: ASCII, UMB, SDI12, MODBUS
