The Acclima True TDR-315H is a high-precision Soil Smart Series sensor designed for simultaneous measurement of soil moisture, temperature, bulk electrical conductivity (BEC), relative permittivity, and pore water electrical conductivity. Using advanced True Time Domain Reflectometry (TDR) technology with sophisticated waveform analysis, it delivers highly accurate and repeatable measurements across all mineral soil types without requiring soil-specific calibration.
Designed specifically for shallow horizontal installations, the TDR-315H features extended 15cm stainless steel waveguides that provide a larger sampling volume for improved measurement accuracy. Its ultra-low power consumption, fast response time, and high-resolution waveform digitization make it ideal for long-term field deployment in power-conscious monitoring systems.
The sensor communicates through an SDI-12 Version 1.4 digital interface, ensuring seamless integration with data loggers, weather stations, irrigation controllers, and environmental monitoring systems. Its waterproof epoxy-filled housing, UV-resistant cable, and rugged stainless steel construction provide dependable performance under demanding outdoor conditions.
