Delta-T Devices is a market leader in soil moisture monitoring, with more than fifteen years experience of providing researchers with high quality soil moisture and temperature sensors. Our range of sensors incudes the “gold standard” ML3 ThetaProbe soil moisture sensor, highly respected by scientists and researchers worldwide for its exceptional accuracy and reliability.

The Delta-T Devices PR2 Profile Probe offers convenient soil moisture profiling to a depth of up to 1 metre. Researchers and consultants appreciate the flexibility of this instrument which can be used in fixed installations or as a portable profiling tool. Combining the Profile Probe with the portable HH2 Moisture Meter and a compatible data logger (such as the Delta-T GP2) creates powerful, integrated soil monitoring solutions.

The SM300 Soil Moisture Sensor offers affordable and good quality measurements of soil water content and soil temperature in a compact and field-robust probe. Industrial grade cables and connectors can be conveniently extended to 100 metres.

The SM150 Soil Moisture Sensor is our most cost effective sensor for obtaining reasonably accurate soil moisture measurements without compromising robust build quality and long term reliability. The SM150 Soil Moisture Sensor is compatible with all Delta-T Devices Data Loggers and for convenience it uses the same cabling system as the SM300.

For instant measurement the SM150 Kit is available, comprising an SM150 Soil Mositure Sensor, a dedicated HH150 Meter and a carry case.

The WET Sensor is proven in the accurate measurement of water content and pore water EC in a range of soils and substrates. It is the ideal tool for fertigation monitoring in horticulture and for the easy assessment of soil salinisation.

Soil Water Potential measurements can be obtained using the EQ2 Equitensiometer, or the SWT4 and SWT5 water filled Tensiometers.
