Soil moisture
SOIL MOISTURE SENSOR PI54-D
The PI54-D soil moisture sensor has a larger volume of influence. It determines volumetric water content (VWC) by measuring the dielectric constant of the soil using capacitance technology and soil temperature. It is 10 cm long and thus measures 1 liter of soil, while high frequency minimizes salinity and textural effects which makes PI54-D accurate in most soils.
Necessary Interface to connect this sensor with iMETOS: 600069 / 900052, 600068 / 900051, 600167 / 900057 or 900173, 900174, 900175.
AQUACHECK SUB-SURFACE PROBE
The Aquacheck sub-surface soil moisture probe offers capacitance based soil moisture and temperature measurements along the vertical soil profile. Different configurations are available with 6, 8 or 12 sensors for a probe length variable from 600 to 1200 mm.

SENTEK DRILL & DROP
Sentek Drill & Drop probe provides the user with great flexibility for precision monitoring of temperature, water and salinity (Triscan) at multiple depths in a soil profile. Available in five lengths: 10 cm, 30 cm, 60 cm, 90 cm and 120 cm with sensors fixed at every 10 cm increment.

IRROMETER WATERMARK SOIL MOISTURE SENSOR
The Watermark Sensor consists of two concentric electrodes buried in a special reference matrix material that is held in place by a synthetic membrane. The matrix material has been selected to reflect the maximum change of electrical resistance over the growth range of crop production, as well as to neutralize the effect of soil salinity. In operation, soil moisture is constantly being absorbed or released and the electrical resistance between the electrodes changes. This resistance is read and logged by the weather station.
The sensor is manufactured from non-corrosive materials and lasts up to three years.

IRROMETER TENSIOMETER
The instrument measures soil water tension (or suction). This value represents the energy a plant’s root system uses to draw water from the soil. Understanding soil moisture dynamics helps the user make informed irrigation scheduling decisions, resulting in improved yield quantity and quality while reducing water, fertilizer, labour and energy costs. Available in different lengths: 15 cm, 30 cm, 45 cm, 60 cm and 90 cm.
