  Tubular probe
  

  EnviroScan probes continuously record the water content in the soil profile. Depending on equipment with soil moisture or TriSCAN sensors, the salt and fertiliser content (quantity of dissolved ions in the soil water) can be measured in addition to soil moisture. The soil moisture is measured using FDR (Frequency Domain Reflectometry). Usually, 16 sensors may be placed on a probe in flexible depth (atintervals of 10 cm). This system issuitable both for measurements near the surface (starting from 10cm) and for depth measurement (> 40 m). The use of different interfaces (e.g. RS232, RS485, SDI-12, Voltage, Modbus) means that the probes can be connected not only to Sentek systems such as SentekPLUS and Sentek SOLO but also to a large number of other data loggers. The data can be read out using GPRS via the Internet or in situ using the connection cable. The sensors are located in the installation tube. This therefore avoids direct contact with the soiland means that the probes are easier to maintain if required. If installed correctly, the soil structure is not disturbed so that the actual water movement in the surrounding soil can be recorded.
