Overview
The award winning EnviroSCAN probe is the flagship product of Sentek. It provides the user with great flexibility for precision monitoring of volumetric water content at multiple depths in a soil profile. The EnviroSCAN probe first made its mark in irrigated agriculture, resulting in water savings of 30-50% and substantial yield and quality benefits. Today it is widely used in all forms of agriculture (irrigated and dryland), environmental applications, research and education, as well as turf, parks and gardens. The EnviroSCAN probe is the only commercially available product that allows for monitoring to great depths (up to 40 meters) using the same profiling probe.

The Technology
Sentek sensors utilize capacitance-based technology to provide near continuous measurements within the soil profile. By creating a high frequency electrical field around the sensor, extending through an access tube into the surrounding soil, the sensors detect the changes in the dielectric constant, or permittivity, of the soil over time. At high frequency, the measurement is affected predominantly by water molecules. The greater the amount of water, the smaller the frequency measured between the two brass rings of the sensor.

EnviroSCAN Sensor
The soil moisture sensor gives an output in volumetric water content (mm of water per 100mm of soil measured). This is converted from a scaled frequency reading using a default calibration equation, which is based on data obtained from numerous scientific studies in a range of soil textures. User-defined, or site specific calibration equations can be applied to each individual sensor to provide a high level of accuracy. Sentek's soil moisture sensor is suitable for use in all soil types under all conditions of soil water content, from saturated to oven dry.

Additional Features

  • Multiple sensors with flexible depth placement (at 10 cm increments)
  • Monitoring from shallow depths (0 - 10 cm) to deep installations (> 40 meters)
  • Length of probe customized to suit the application (probe length adjustable in the field)
  • Up to 16 sensors on one probe (moisture or moisture/salinity)
  • Built-in probe orientation and depth settings to enhance sensor repeatability
  • Full serviceability
  • Flexible connectivity for wide range of data retrieval options
