soil volumetric water content sensor


  • The TEROS 10 water content sensor from METER Group (formally Decagon Devices)
  • Calibrated, robust, and reliable water content sensor
  • Ideal for soils or substrates in the field, glasshouse, pots, or laboratory
  • Analog output to connect to most data loggers
  • Or portable measurements with the Procheck handheld meter
  • Replaces the older models of GS1 and EC-5 sensors

The TEROS-10 is a low-cost, ruggedized sensor for the measurement of soil volumetric water content. The TEROS-10 can accurately measure the moisture content in soil or soilless media.

The TEROS-10 is ideal for scientific researchers, growers, nurseries, and glasshouses with pots or artificial substrates. The robust sensor design, plus flexible output to connect to most data loggers or systems, makes the TEROS-10 ideal for monitoring water content.

The TEROS-10 is sensitive across the entire water content range. It can be installed in dry desert soils or in very wet peat. Sensitive to small changes in water content anywhere from 0 - 100% VWC.

Install the TEROS-10, plug it into the ZL6 data logger, set the measurement intervals, and start logging data. No programming required. The scientists and engineers at Edaphic Scientific can assist in connecting the TEROS-10 to your existing system. The TEROS-10 has a voltage output and is compatible with most data logging systems.

Sap Flow MeterEdaphic Scientific is a one-stop shop for a whole system monitoring solution. We provide plant and soil monitoring systems for researchers and growers.

Our systems not only support soil moisture sensors but related sensors such as sap flow, dendrometers, soil oxygen, weather parameters, and more.

At Edaphic Scientific, we want to work with you from the start of your project through to its completion. We can provide:

  • Assistance with project and experimental design
  • Procurement of all monitoring equipment, including sensors, data loggers and data management software. Edaphic Scientific is a one-stop shop where we can source and find any necessary equipment for your project from our preferred suppliers or third-party suppliers
  • Installation and training
  • On-going assistance with data interpretation and equipment maintenance
  • Data correction and analysis, including statistical analysis with the R-package
  • Report and publication preparation, including tables, figures, graphs, and manuscript writing


advanced data collection and management solutions

Edaphic Scientific recognises the need for flexible and adaptable sensor and data logging solutions for experimental or environmental monitoring projects.

Data can be downloaded directly in the field from data loggers. A direct connection between the data loggers and your computer, via a USB cable, can be used for the manual downloading of data.

Alternatively, data can be downloaded over the internet on your iPhone, iPad or desktop computer with the Eagle.io cloud-based data management software solutions. Through this remote based downloading capabilities, you can download, view and manage your data and system, anywhere in the world and at any time.
