TEROS & ECH2O

MEASURE SOIL WATER

Volumetric water content, soil water potential, and more

ECH2O SOIL MOISTURE

Among the thousands of peer-reviewed publications using METER soil sensors, no type emerges as the favorite. Discover all our volumetric water content sensors.

Which soil sensor is perfect for you?

When choosing between METER’s soil sensors, the first thing to know is that all METER soil sensors have the same research-grade accuracy with minimum sensitivity to salts (10 dS/m bulk EC), …

Using soil water sensors for efficient irrigation in greenhouses.

Soil water sensors provide promising new opportunities for automating greenhouse irrigation according to plant need.

THE ONLY WORRY-FREE SOIL WATER POTENTIAL SENSOR

You may expect to see a high price-point for all of the extra value we engineered into TEROS 21. Instead, we offer them at low cost so you don’t have to spend more money to get the measurement coverage you need.

Soil moisture sensors—how many do you need?

The number of soil moisture sensors installed at a research site can make the difference between proving a hypothesis or missing it entirely. How many sensors will produce the most complete soil moisture picture?

Which installation method is best?

Patterns of water replenishment and use give rise to large spatial variations in soil moisture over the depth of the soil profile. Accurate measurements of profile water content are …

DISCOVER ALL TENSIOMETERS

As world experts in soil-plant-atmosphere measurements, we developed the tensiometer product line with the highest accuracy for soil water tension measurements in the lab and the field.

WATER POTENTIAL IN THE LAB

With the T5 Tensiometer, we put our 25 years of expertise to work in the smallest space possible: a ceramic tip with a surface area of ​​only 0.5 cm2. The T5’s minor footprint allows major advantages over larger tensiometers such as very little soil disturbance and an incredibly fast response time.

Measurement volume of METER volumetric water content sensors

One of the most important factors to evaluate when selecting a soil moisture sensor is the volume of soil that the sensor integrates into the volumetric water content (VWC) measurement. For some applications, a sensor with a small measurement volume is desirable.

CONNECT YOUR SOIL MOISTURE DATA

To connect a weather or climate sensor, just plug it into one of the six ports, and the EM60 data logger automatically recognizes it.

Defining water potential

Water potential is the energy required, per quantity of water, to transport an infinitesimal quantity of water from the sample to a reference pool of pure free water.
