We have condensed the true TDR measurement method, which was only possible with large systems, into a compact sensor.
The M2980CM-426SHE condenses a true TDR measurement method, which was only possible with traditional large systems, into a compact sensor thanks to breakthrough technology. Traditional small sensors referred to as TDR actually employed simplified measurement methods, but the M2980CM-426SHE measures true dielectric constant using a revolutionary TDR method that is currently patent pending. In fact, waveform data can be obtained from this compact sensor. The M2980CM-426SHE is a standard model that is compatible with many soil types and is optimized for low power consumption. The M2980CM-426SNE is a model suitable for high salinity soils, although it has higher power consumption. The M2980CM-421SWE is a model with a rod length of 10 cm, designed for spaces with restrictions, such as rock wool or cultivation pots. It can be directly connected to a data logger and, like TDT soil moisture sensors, is maintenance-free, allowing for long-term continuous observation. It can measure not only soil moisture (volumetric water content) but also electrical conductivity (EC), temperature, and dielectric constant in the soil.

basic information
■Features ● It can be inserted into the soil due to its needle-like rod shape. ● Capable of measuring not only soil moisture (volumetric water content) but also electrical conductivity (EC), temperature, and dielectric constant in the soil. ● SDI output ● High accuracy and long-term stability ● Can measure in clayey soils and soils with high salinity ● Potential for measuring moisture content in grains ● Since it can measure the apparent dielectric constant (ε), a unique formula (ε-θ relationship) tailored to the soil can also be utilized ● Response improved by 30% compared to the old type
