RG1 Tipping Bucket Rain Gauge
The Standard RG1 Rain Gauge was designed as a universal rain gauge, that is suitable for most applications. There are two versions of the RG1 available: 0.2mm and 0.1mm.
ET Weather Stations
Evapotranspiration (ET) is regarded as water loss from the Earth's surface from evaporation and plant transpiration. Evapotranspiration is typically expressed in mm/day or inches/day. Although all weather station parameters are required for accurate evapotranspiration monitoring, air temperature and humidity, solar radiation and windspeed and direction are required in the Penman Monteith method of computing the reference evapotranspiration (Eto). The Penman Monteith method of ETo computation is based on two equations: (i) an energy equation (solar radiation) and an aerodynamic equation (using wind and air humidity). Soil moisture probes and other sensors (like dendrometers) are also being used today to fine tune ETo. ETo stations are often used for predicting irrigation scheduling and disease monitoring in agriculture. A typical ETo station is therefore composed of the following components:
- A753 addWAVE RTU with solar panel
- SEN-R Combi sensor for air temperature and humidity
- SP-Lite Silicium-Pyranometer from Kipp&Zonen
- WIN Combi sensor for wind speed and direction
- RG Rain gauge
- Pole set to mount the station
