Three-electrode probe for the measurement of the soil volumetric water content. RS485 MODBUS RTU output. Cable length 10 m.

Measure the soil volumetric water content (VWC) by using a capacitive measurement principle which allows fast measurements in the field and with minimal invasiveness. The three electrode probe is particularly suitable for the measurement in small volumes, for example for cultivations in pots.
The probes give a direct reading in Volumetric Water Content (VWC) from 0-60%.The version with RS485 digital output with MODBUS-RTU protocol allows the use of even very long connection cables. It can be connected to the data loggers with RS485 MODBUS-RTU input.
The version with SDI-12 digital output is compatible with version 1.3 of the protocol and can be connected to the data logger with SDI-12 input.
The version with analog output has two 0.5…3 V standard voltage outputs: one for the volumetric water content and one for the temperature. On request, 0…2.5 V, 0…5 V or 0…10 V outputs.
The probes are equipped with a fixed cable, 5 or 10m standard length, with open wires at the end.
