DS-2 Sonic Anemometer

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.

SC-1 Leaf Porometer for Stomatal Conductance Measurements

Accurate, affordable, and practical stomatal conductance. The SC-1's breakthrough steady-state technology provides accurate stomatal conductance measurements from an affordable, research-grade instrument. No moving parts, tubes, or fans simplify the operation and maintenance of the porometer.

Spectral Reflectance Sensor (SRS)

The Spectral Reflectance Sensors (SRS) are two band radiometers designed to measure the Normalized Difference Vegetation Index (NDVI) or Photochemical Reflectance Index (PRI). The SRS are designed for long term field deployment to continually monitor changes in NDVI or PRI related to canopy growth, senescence, stress, and productivity.

Water Potential

Water potential measurements are used to determine whether or not water will move and to predict where it will go. Use these sensors to measure water potential across the entire range.

Smart Field Lysimeter Weighable Controlled Tension Lysimeter

Large-scale lysimeter measurements in a smaller package and at a lower price. A complete small, weighable, tension controlled field lysimeter; combined with tensiometers, soil moisture sensors, data logger with optional GPRS modem, lightning protection, and powered by solar panels.
