soil moisture, temperature & EC sensor

Soil Moisture and Salinity SensorThe SMEC300 is a low cost, high accuracy probe for the simultaneous measurement of soil volumetric water content, temperature and electrical conductivity (EC – salinity).

Based on the capacitance measurement principle, the SMEC300 is ideal for researchers, students and growers for scientific experiments in the field or glasshouse, or for monitoring irrigation and fertigation.

The SMEC300 is only compatible with the Soil Sensor Reader for portable, handheld measurements or the WD2400 Watchdog Data Logger for in-situ, continuous measurements.
