DescriptionThe 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.

Key Features:

• Waveform Digitizing TDR with 5ps Resolution

• Measures Water Content: 0% to 100% VWC

• Reads Bulk EC: 0 to 2000 µS/cm

• Accurate Soil Temperature: ±0.25°C

• Supports Time Domain Waveform Download

• Ultra-Fast Incident Wave Rise Time: 150ps

• Fast Measurement Response: <0.25 sec

• Low Power Usage: 0.09 J per Reading

• SDI-12 Interface

Measurement Functions:

• Volumetric Water Content (VWC): 0% to 100%

• Medium Permittivity: 1 to 80

• Medium Bulk Electrical Conductivity (EC): 0 to 2000 µS/cm

• Medium Temperature: -40°C to +60°C

• Pore Water EC (Hilhorst Model): 0 to 55,000 µS/cm

Applications:

• Agriculture, Turf, Landscaping, Orchards, Greenhouses, Golf Courses, and Nurseries

• In-Situ Soil Water Monitoring for Agriculture

• High Credibility Data for CloudBased Analysis

• Gold Standard VWC Reference

• Replacement for Neutron Probes

• Portable Measurements

• Laboratory and Field Research Instrumentation

The EarthScout TDR Soil Moisture Sensor is the gold standard for reliable, high-accuracy soil moisture measurement, offering fast, energy-efficient readings for a wide range of agricultural and scientific applications. text goes here
