soil sensor reader

Soil Moisture SensorA low cost, simple and easy-to-use, palm-sized reader for the SM100 and SMEC300 soil moisture, temperature and salinity sensors.

Spot-check your soil volumetric water content, temperature and/or salinity in the field, laboratory, glasshouse or greenhouse.

The Soil Sensor Reader is ideal for checking the water content of pots or shallow soils. It is also ideal for students and teaching

Adaptors are available to read our gypsum blocks (soil water potential) and a range of environmental sensors.

SM100 – volumetric water content sensor

The SM100 sensor is ideally used in combination with the Soil Sensor Reader for measurements of soil volumetric water content.

Based on the capacitance, or frequency domain, measurement principle, the SM100 is pre-calibrated with the Soil Sensor Reader to provide direct readings of soil moisture. The Soil Sensor Reader also displays raw data from the SM100 sensor so you can perform your own, soil specific calibration curve.

The SM100 is ideal for light, or porous soils, such as potting mixture and sands. It can be used in the glasshouse for student teaching or honours or postgraduate research projects.

SMEC300 – soil moisture, temperature and EC sensor

The SMEC300 sensor is ideally used in combination with the Soil Sensor Reader for measurements of soil volumetric water content, temperature and electrical conductivity (EC).

The SMEC300 is similar in function to the SM100 sensor, however it has the added features to measure temperature and EC (or salinity) of soils. Therefore, the SMEC300 is ideal for projects that require knowledge of EC dynamics – such as salinity or nutrient dynamics in the soil.

Similar to the SM100, the SMEC300 is ideally used in porous soils or media such as potting mixture and sands.

Gypsum Block – soil water potential sensor

A popular approach to measuring soil water potential, or soil tension, is the gypsum block. The Watermark Gypsum Block measures the matric potential of the soil between 0 and -200 kPa (centibars) and is an ideal approach to determine soil water status for optimal crop growth. The gypsum block can be buried to any depth in the soil profile.
