Integrate Climate Variables Account for environmental variables with simple, accurate, plug-and-log sensors. Get Local Weather Measure weather data where you are, not 5 miles away at the Met tower, so you can measure environmental variation on an…
Our lowest-cost soil moisture sensor. Measures Volumetric Water Content only. Just 5 cm long with a 0.3 L measurement volume, this handy little sensor is easy to install in the field and can also be used in nursery pots.
PAR is often used to generate interception, which is then used to predict biomass production, crop growth, etc. This simple, no-frills sensor measures photosynthetically active radiation over your chosen interval. Plug-and-log simplicity when used with the Em50 line of data loggers.
Measure wind speed and direction over your chosen interval. Straightforward setup. Plug-and-log simplicity when used with the Em50 line of data loggers.
SC-1 Leaf Porometer Video Accurate, Affordable, Practical Stomatal Conductance The SC-1's breakthrough steady-state technology makes accurate stomatal conductance measurements affordable and practical for everyday research. No Moving Parts Steady…
Measure Canopy PAR and Calculate LAI The AccuPAR is a lightweight, portable photosythetically active radiation (PAR) sensor wand that lets you measure canopy PAR interception at any location within a crop or forest canopy. PAR data can be used…
Total solar radiation data is used to calculate an energy balance, to distinguish between latent heat flux and sensible heat, and as in input in the Penman-Monteith equation, among other things. This simple, accurate sensor allows you to measure total solar radiation over your chosen interval. Plug-and-log simplicity when used with the Em50 line of data loggers.
Measures air temperature and relative humidity and outputs both values as a digital signal. Comes with radiation shield. Plug-and-log with the Em50 line of data loggers.
Our full-featured soil moisture sensor. Measures volumetric water content, temperature, and electrical conductivity in soil. This three-pronged, 5 cm long sensor is for use in soil only. High frequency oscillation and patented signal filtering deliver excellent accuracy with minimal textural effects. Serial or SDI-12 communication give lots of options for integrating into systems run by other data loggers (including Campbell Scientific).
Detect wetness and ice formation with a sensor that closely mimics the wetness state of real leaves. No painting or user calibration required. Plug-and-read with the Em50 series of data loggers.
Radiation data is important in calculating an energy balance, in determining latent heat flux vs. sensible heat, in generating interception data for biomass and crop growth models, and for use in the Penman-Monteith equation. We offer both total solar radiation and photosynthetically-active radiation sensors.
