Meter ECH₂O 5TE

Soil moisture, temperature, and electrical conductivity

The 5TE monitors bulk electrical conductivity (EC), in addition to volumetric water content (VWC) and soil temperature.

Monitor salt levels

The 5TE enables users to measure the EC response to salts and fertilizers in the soil. EC Measurements require good contact between the stainless steel electrodes on the sensor, and the soil. In potting soil and soilless medias, we recommend using the GS3 to maintian good soil contact and compensate for air gaps in the substrate.

Engineered for accuracy

The 5TE determines VWC by measuring the dielectric constant of the media using capacitance/frequency domain technology. The sensor uses a 70 MHz frequency, which minimizes salinity and textural effects, making the 5TE accurate in most soils. The 5TE measures temperature with an onboard thermistor, and electrical conductivity using a stainless steel electrode array. VWC in mineral soils is calculated using the Topp equation; other calibrations are provided on request. Temperature and electrical conductivity are factory calibrated for all soil types.

Easy installation

The 5TE’s small size makes it easy to install in the field and the greenhouse. This robust sensor should be pushed directly into undisturbed soil to ensure good accuracy.

Easy integration

Each 5TE comes standard with serial and SDI-12 communication options, meaning easy integration with systems manufactured by other companies.
