Sensors

product-shots-5TE - Copy5TE:

The 5TE allows you to manage salts in your system by monitoring bulk electrical conductivity, as well as the volumetric water content and temperature of your soil. All three of the 5TE measurements are made independently, and the sensor uses a 70 MHz frequency, minimizing salinity and textural effects and making the 5TE accurate in almost any soil.

product-shots-5TM - Copy5TM:

The 5TM delivers temperature with its onboard thermistor, along with volumetric water content. VWC is measured by taking the dielectric constant of the soil using capacitance/frequency domain technology. The 5TM is accurate in a wide range of soils and soilless media.

product-shots-gs3 - CopyGS3:

The GS3 has Decagon’s signature accuracy and low cost, and is designed specifically for use in soil-less substrates. This sensor measures water content, temperature, and EC independently. Its 70 MHz frequency minimizes textural and salinity effects making it accurate in almost any soil or soilless media.

MPS-2 and MPS-6

The MPS sensors measure a wide range of soil water potentials without user maintenance or calibration. MPS sensors can simply be packed into a hole, plugged into a data logger, and left to measure water potential data. MPS sensors are the only calibrated maintenance-free water potential sensor on the market.

product-shots-CTD - CopyCTD:

The CTD sensor is a low cost, accurate tool for monitoring of water level, electrical conductivity and temperature.  The sensor utilizes a vented pressure transducer to get accurate water level measurements from 0 to 3.5 m, removing the effects of barometric pressure.  With a range of 0 to 120 dS/m, the CTD sensor has the ability to make accurate electrical conductivity measurements in a broad range of applications.

VP-4:

Use the rugged VP-4 sensor to measure relative humidity, temperature, vapor pressure, and barometric pressure together with with soil moisture probes in microclimate and evapotranspiration studies. This compact little 5 cm x 2 cm sensor is able to fit into the smallest of spaces, and thanks to its unique Teflon screen, the relative humidity sensor can survive a deluge. The screen protects the sensor from liquid water and dust without limiting diffusion of water vapor, thus, the protected sensor is still able to quickly respond to changes in humidity.

Converted_file_3a13e45dDS-2 Sonic Anemometer:

The DS-2 is a rugged, research-grade two-dimensional sonic anemometer built specifically for agricultural, forestry, and environmental research applications. A lower wind speed threshold of 0 m/s makes the DS-2 especially well-suited for measuring wind within plant canopies, where wind speeds are often below the threshold of a cup anemometer. And with a resolution of 0.01 m/s, the DS-2 can record fine-scale variations in wind speeds.

product-shots-srsSpectral Reflective Sensor (SRS):

The SRS is a matchbox-sized, multiband radiometer that can be mounted on a fence post, tripod, or meteorological tower. It allows you to measure NDVI or PRI vegetation indices at the plot or plant stand scale, and allows for non-destructive sampling of canopy greenup, senescence and plant stress. It’s inexpensive enough to deploy multiple sensors simultaneously, and rugged enough to leave in the field for an entire growing season, if not longer.

ES-2ES-2:

The ES-2 Electrical Conductivity Sensor is designed to measure the electrical conductivity of water in a pipe or tank.  When you pair the new ES-2 with a GS3 or 5TE in the soil, you’ll begin to develop a complete picture of the salts that are going into your system as well as the salts remaining in your soil or substrate.

GS-3 EditedDrain Gauge G3:

The Drain Gauge G3 Passive Capillary Lysimeter allows you to determine the volume of water and chemicals draining from the vadose zone into the groundwater. The one-and-a-half meter tall Drain Gauge is buried directly in the ground to measure flow rate in unsaturated soils and collect soil water samples for chemical analysis. Water samples can be collected easily through a surface port to analyze for chemicals, fertilizers, and other contaminants. Flux rate, electrical conductivity, and temperature are constantly monitored through an internal sensor (optional, but this sensor is what communicates in SDI-12).
