The SoilVUE™10 is a soil water content profile sensor powered by Campbell TrueWave™TDR technology. This soil moisture, electrical conductivity, and temperature profile sensor was developed with environmental researchers and environmental monitoring networks in mind. The SoilVUE™10 represents several exciting advancements in in-situ soil measurement that should make this an extremely compelling option for anyone in these applications who needs to make multiple measurements in a profile.
Campbell Scientific’s proprietary TrueWave™TDR technology combines a best-in-class rise time with an advanced waveform analysis technique to determine the true travel time of a high-frequency pulse. This process achieves a high-resolution, smooth signal for measurements that are defensible and can be universally compared with other TDR measurements. Not all TDR-based sensors perform equally well.
The SoilVUE™10 consists of TDR circuitry connected to a series of six or nine helical wave guides that make up part of the overall threaded design. The threaded design with individual sensors built into the threads improves sensor contact with the soil to reduce potential error from air gaps. The TDR circuitry generates a short rise time electromagnetic pulse that is applied to the helical wave guides. The elapsed two-way travel time of the applied pulse is used to calculate the dielectric permittivity of the surrounding media and determine the volumetric water content using a mixing model.
The soil water content profile sensor can be installed in a hole made by a standard 5 cm (2 in.) hand auger. Excavation machinery or expensive custom tools are not necessary to install the sensor.
The included cable has an IP67 rated M12 connector that is detachable from the sensor for easy field replacement if the cable becomes damaged.

The CE4 is a current-excitation module that applies a constant current to the heating element of up to four 229 Heat Dissipation Water Matric Potential Sensors. A current-excitation module is required when you use 229 sensors to measure soil water matric potential. Benefits and Features Provides exc
Soil moisture sensors that measure the moisture tension in the soil are read out with the soil moisture meter Watermark. The measuring principle is similar to that of the gypsum block system. The special sensors however do not dissolve in the soil and have a more consistent distribution of pores so that more accurate measurements are possible. Benefits Soil Moisture Measur
The kit comprises an SM150T* Soil Moisture Sensor, a dedicated HH150 Moisture Meter and a carry case. The cable and connector are watertight – an essential requirement for potentially wet environments. The HH150 Meter displays volumetric water content (% volume). Please note that although the SM150T Sensor has a built-in temperature sensor, the HH150 Moisture Meter does not measure or display temperature.
With the Rhizon soil moisture sampler we supply a range of miniature soil moisture samplers. The Rhizon samplers are used for repeated and reliable sampling of all dissolved components in the soil solution. The porous plastic material (PES) wets spontaneously and has standard 0.15 micron pores. The samplers are supplied with coextruded tubing (PE inside / PVC outside) 1 mm internal diameter, luer connector and protective cap. The sampler is reenforced by a wire.
