The SM300 measures soil moisture and temperature with research grade accuracy.

Research grade sensor
The market leading SM150-T offers outstanding performance in normal and saline soil conditions, and is stable across wide ranges of temperature and salinity. Its construction uses industrial grade connectors and high specification materials throughout to produce a soil moisture sensor of outstanding quality. The built-in temperature sensor simplifies soil temperature measurement and achieves 0.5 °C accuracy.

Ease of use
Versatile cabling solutions
Easy installation at depth
Minimal soil disturbance
Compact – can be used in plant pots

The SM150-T minimises soil disturbance, preserving the original soil structure around the measurement rods. It is easy to insert and install whether at the soil surface or at depth. The SM300’s circular shape facilitates installation in- augered holes – extension tubes are available.

Calibration
The SM150-T is provided with general calibrations for mineral and organic soils. A two-point soil specific calibration can be performed for greater accuracy if required.
