Soil Moisture plus Temperature Sensor

The SM300 from Delta T-Devices measures soil moisture and temperature with research grade accuracy: Soil moisture and temperature; Dependable accuracy ± 2.5%; Good temperature and salinity stability and Easy data logger connection (0-1V).

The SM300 offers outstanding performance in mineral, organic and saline soil conditions, and it is stable across wide ranges of temperature and salinity. The SM300’s 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.

The SM300 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.

The SM300 is a dual-purpose probe – it can be used both with the Delta-T HH2 hand-held Moisture Meter for instant moisture readings, or left in situ for data logging of moisture and temperature.

The SM300 is compatible with all Delta-T data loggers; they provide cost effective solutions for recording up to 60 sensors. In fact the SM300 can be connected to most types of data logger (simple 0 to 1V DC output for water content).
