Soil Cub

SOIL CUB – Soil Moisture Meter with digital EarthScout TDR SDI-12 Soil Moisture Sensor is loaded with great benefits:

• Just insert the EarthScout TDR SDI-12 Soil Moisture Sensor in the soil and tap the box for an instant reading of soil moisture, soil temperature, soil EC, air temperature, and air humidity

• Easy to use

• No assembly required

• Digital, Time Domain Reflectometer (TDR) SDI-12 soil moisture sensor is research-grade and considered the gold-standard for precision and accuracy by scientists at leading universities

• EarthScout TDR SDI-12 sensor is stainless steel, corrosion resistant, commercial-grade, extremely durable, and does not require calibration

• Portable

• Water resistant case

• Requires 6 AA batteries

• 1 year limited warranty

The EarthScout TDR (SDI-12) Soil Moisture Sensor is a precision Time Domain Reflectometer (TDR) that provides highly accurate volumetric water content (VWC) measurements in soils and other porous media. Trusted by leading researchers, it offers the same TDR technology found in high-end instruments that cost thousands of dollars more. Compact yet powerful, it integrates precision TDR components and a 15 cm waveguide within a small enclosure.

Key Advantages:

• High-Resolution TDR Technology: Delivers 5ps resolution for precise water content measurements (up to 1.00 m³/m³), using advanced waveform digitizing and analyzing firmware for precise time-domain analysis.

• Improved Sensitivity: Direct coupling of the TDR function to the waveguide eliminates coax cables, enhancing bandwidth, resolution, and measurement sensitivity.

• Fast Performance: Ultra-fast rise time (150ps), rapid response (<0.25 sec), and low power consumption (0.09 J per reading) make it ideal for both field and laboratory use.

• Robust and Reliable: VWC readings are unaffected by bulk electrical conductivity (under 1.8 dS/m) and soil compaction, eliminating the need for soil-specific calibration.

• Durable and Energy-Efficient: Low sleep current (<10 µA) supports long battery life.
