The “gold standard” ML3 ThetaProbe soil moisture sensor is highly respected by scientists and researchers worldwide for its reliability and 1% soil moisture accuracy. In addition to soil water content measurement it features built-in temperature measurement (when buried).
We also offer the SM150T soil moisture and temperature sensor with 3% soil moisture accuracy – well suited to a wide range of soil science and horticulture applications.
For vertical profiling of soil moisture our PR2 Profile Probe (analogue & SDI-12 versions available) is ideal. The PR2/4 soil moisture probe measures soil moisture at 4 depths down to 40cm and the PR2/6 soil moisture probe measures at 6 depths down to 100cm.
Our WET Sensor is a powerful tool for fertigation monitoring in horticulture or for soil salinity studies. It measures three vital properties of substrates: water content, pore water EC and temperature.
For soil water potential (soil water tension) measurements we offer the EQ3 Equitensiometer – featuring maintenance-free operation and a wide measurement range.
Our sensors are compatible with most types of data logger, including our GP2, GP1 and DL6 – or can be connected to a hand-held readout unit (such as the HH2 Soil Moisture Meter).
