Soil Moisture & Temperature Sensor

Soil Moisture & Temperature Sensor

150/E10

This dual purpose sensor produces soil moisture and temperature measurements.

This sensor works by by measuring the dielectric constant of the soil thus allowing the calculation of volumetric water content.

Apparent Dielectric Permittivity (εa) Range 1 εa to 80 εa

Apparent Dielectric Permittivity (εa) Resolution 0.1 εa from 1-20, <0.75 εa from 20-80

Apparent Dielectric Permittivity (εa) Accuracy ±1 εa​ from 1-40, 15% from 40-80

Soil Volumetric Water Content (VWC) Resolution 0.08% VWC from 0 to 50% VWC

Soil Volumetric Water Content (VWC) Accuracy ±3% VWC using Topp equation, ±2% VWC using medium specific calibration

Temperature Range -40 °C to +60 °C

Temperature Resolution 0.1 °C

Temperature Accuracy ±1 °C

Dimensions 10 cm X 3.2 cm X 0.7 cm

Cable Length Supplied with 5 m cable. Custom lengths available up to a maximum of 75 m

Measurement Time 150 ms

Output RS232 or SDI-12
