e + SOIL MCT sensor/logger
Eijkelkamp 11.41.11.SA e + SOIL MCT sensor/logger

Product Features
  • Eijkelkamp 11.41.11.SA e + SOIL MCT sensor/logger measurement of Moisture content, electrical Conductivity and Temperature in soils or comparable substrates.
  • Storage of the measurements.
  • Comparison of actual values to preset alarm values (when using telemetry).
  • Transfer of the measurements optically to the user directly or via the e-SENSE telemetry system.
  • Allows for user definable sampling and transfer intervals, which also can be set remotely.
  • The measuring principle of the sensor is based on the Frequency Domain Method (FD), described by Wageningen University & Research Centre (van Balendonck and Hillhorst), at a frequency of 20 MHz, from which the system derives permittivity, conductivity and temperature.
  • The sensor contains a dedicated chip developed by the Institute of Agricultural and Environmental Engineering in Wageningen, the Netherlands and amicrocontroller data logger with embedded software that will allow for a range of applications, e.g. the sensor can derive from its data, such as volumetric water content and bulk electrical conductivity (ECb).
  • The internal software can automatically compensate the conductivity for the measured temperature.
  • From a range of different soil types the moisture content will be accurately measurable, based on general calculation models (e.g. TOPP 2001 model) and local calibration data.
  • Soil specific calibration is possible with a 2-point calibration which can be set up by the user.

W.E.T. Sensor
Eijkelkamp 19.33 W.E.T. Sensor

Product Features
  • Eijkelkamp 19.33 W.E.T. Sensor to measure pore water conductivity and temperature in the top layer of a soil.
  • The measurement values are shown on the display of the hand held meter and can be stored in the memory (including time and sensor location). These data can be read on a PC.
  • The WET sensor measures three vital soil properties directly within the soil: Water content, Electrical conductivity and Temperature.
  • The sensor is unique in its ability to measure pore water conductivity, which is the EC of the water that is available to the plant.
  • Traditionally this measurement has been made by the time-consuming and error-prone method of extracting pore water from the soil by suction, before measuring it with a standard conductivity meter.
  • In contrast, the WET sensor is simply pushed into the soil (or other growing medium) and then read directly using the hand held meter.
  • The standard set includes the WET sensor, a hand held meter, the software and a carrying case.

Soil Moisture Monitoring
Soil Moisture Monitoring

Product Features
  • To accurately measure and record the soil moisture in most locations.
  • The system employs low cost gypsum blocks to measure the electrical resistance of the soil.
  • The resistance value is converted into a soil suction measurement (in units of bars).
  • The gypsum block or blocks are connected to a data logger in a waterproof enclosure that is mounted on a pole or a frame with a tripod base, depending on the permanence of the installation.
  • The data logger will measure, store and display soil measurement data for about one year using the logger’s internal battery.
  • Can be done over landline, cellular, and radio communication links, whichever alterative is available and most cost effective at the installation site.
