SUBSTRATE SENSOR

Get high precision EC and VWC measurements.

Real-time rootzone data

Not all substrate sensors are the same. This is the ultimate substrate crop steering tool. Now you’ll know better, so you can grow better.

Precise readings

The AROYA® TEROS 12 rootzone sensor combines a 70 MHz circuitry with an extremely ruggedized epoxy fill and securely- attached sharpened stainless steel needles, that easily slip into any growing substrate and are resistant to salts, so you can worry less about sensor deterioration.

It is designed to collect highly accurate moisture, temperature and EC readings. It measures volumetric water content (VWC) from 0-100%, the substrate, the temperature between -40 and +50℃, and EC in the range 0 to 23 dS/m.

Legendary technology

The AROYA TEROS 12 delivers the best volume of influence to sensor size on the market so you’re less susceptible to varying substrate sizes. Legendary technology with an ultra-rugged form and a new calibration procedure to deliver an unbeatable price-to-performance ratio.

Not all substrate sensors are the same: The AROYA TEROS 12 uses a high-frequency capacitance sensing technique. Learn more about the sensor application in crop steering.

 

Specifications

Volumetric water content (VWC)

Range:
Soilless media calibration: 0.0–1.0 m3/m3


Apparent dielectric permittivity (εa): (air) to 80 (water)

NOTE: The VWC range is dependent on the media the sensor is calibrated to. A custom calibration will accommodate the necessary ranges for most substrates.

Resolution:
0.001 m3/m3


Accuracy:
Generic calibration: ±0.03 m3/m3 (±3.00% VWC) typical in mineral soils that have solution EC <8 dS/m


Medium specific calibration: ±0.01–0.02 m3/m3 (±1–2% VWC) in any porous medium


Apparent dielectric permittivity (εa): 1–40 (soil range) , ±1 εa (unitless) 40–80, 15% of measurement
