Measure horizontal wind speed and direction with our affordable sonic anemometer. The DS-2 is a rugged, research-grade sonic anemometer built specifically for agricultural, forestry, and environmental research applications. The DS-2 is accurate at low wind speeds making it the perfect instrument for measuring wind within and above plant canopies.
Measure wind speed and direction over your chosen interval. Straightforward setup. Plug-and-log simplicity when used with the Em50 series of data loggers.
The simple ECT air temperature sensor is an easy-to-use sensor for measuring the temperature of air (when used with the radiation shield), or other materials.
The VP-4 Vapor Pressure/Barometric Pressure/Humidity/Temp Sensor with Radiation Shield measures air temperature and relative humidity and outputs all four values as a digital signal. Plug-and-log capabilities with the Em50 line of data loggers.
Best for measuring irrigation events, Decagon's ECRN-50 is both self-emptying and frost proof. Plug-and-log capabilities with the Em50 series data loggers.
The ECRN-100 is best used in research studies or for measuring precipitation. Plug-and-log capabilities with the Em50 series data loggers.
Photosynthetically Active Radiation (PAR) is a measure of the light energy used by plants to drive photosynthesis. These measurements are used to estimate photosynthesis, biomass accumulation, and crop growth. This simple, no-frills PAR sensor is weather tight and ready for long-term field deployment, and has plug-and-log simplicity when used with the Em50 line of data loggers.
Total solar (i.e., shortwave) radiation data have a wide range of uses, including distinguishing between latent heat flux and sensible heat, calculating an energy balance, and calculating evapotranspiration using the Penman-Monteith equation. This simple, accurate pyranometer allows you to measure total solar radiation over your chosen time interval. Plug-and-log simplicity when used with the Em50 line of data loggers.
