Watershed Characterization

Data Loggers

Looking for a logger to power your sensors and read and store the measurement data? The Em50 series simplifies data logging with: Pre-programming. No user programming necessary. An internal power supply (5 AA batteries). No external power source…

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.

Davis Cup Anemometer

Measure wind speed and direction over your chosen interval. Straightforward setup. Plug-and-log simplicity when used with the Em50 series of data loggers.

Watershed Monitoring System

EC-5 Lowest Cost Soil Moisture

  • Volumetric water content
  • Lowest cost soil moisture sensor
  • Analog (voltage) output.

ECT Air Temperature Sensor

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.

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.

5TM Soil Moisture and Temperature

  • Volumetric water content and temperature
  • Epoxy overmold for long life
  • Digital, SDI-12

ECRN-100 High-Resolution Rain Gauge

The ECRN-100 is best used in research studies or for measuring precipitation. Plug-and-log capabilities with the Em50 series data loggers.

PAR Sensor

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.

PYR Solar Radiation Sensor

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.
