The new AWS Automatic Weather Station from ICT International provides flexibility, accuracy and value for money.
The AWS is supplied with a preconfigured set of sensors for Air Temperature, Relative Humidity, Barometric Pressure, Wind Speed, Wind Direction, Rainfall, and Solar Radiation or PAR.
The AWS automatically calculates Vapour Pressure Deficit (VPD) and Penman-Monteith Evapotranspiration.
The Weather Station is supplied with a cross arm and basic mounts so it can be attached to any type of customised mast. Alternatively a standard pole mast can be purchased with the system.
Advanced Multi-function Logger. Weather Station Logger – Includes barometric pressure sensor corrected for elevation, 4GB Memory, internal battery, USB and Wireless Communication, IP65 Water proof enclosure and Windows Software.
Combined Met Station Includes: Wind speed and direction, temperature and relative humidity.
Global Solar Radiation Sensor (Pyranometer) with levelling plate. Standard option: 380nm to 1120nm wavelength. 5m cable. Advanced option: 305 to 2800nm, first class pyranometer.
Tipping bucket, stainless steel rain gauge. 0.2mm resolution, 2% accuracy. Cable length: 5m.
