• Measures a 0.3-liter volume of soil
• Smaller measurement volume for use in containers or measuring at multiple depths
• High-frequency (70 MHz) circuit provides good accuracy even in high-salinity and sandy soils
• Compatible with Onset stand-alone and web-based weather stations

An affordable soil moisture smart sensor with a two-tine design for easy installation. This sensor integrates the field-proven ECH2O EC-5 Sensor and a 12-bit A/D, and provides +/-3% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration. Readings are provided directly in volumetric water content. This sensor is designed to maintain low sensitivity to salinity and textural effects.
