The probes HD3910.1 (two electrodes) and HD3910.2 (three electrodes) 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 HD3910.2 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%.

Versions available:

  • RS485 digital output with MODBUS-RTU protocol: allows the use of even very long connection cables. It can be connected to the data loggers HD32MT.1 and HD32MT.3 or to any other data logger with RS485 MODBUS-RTU input.
  • SDI-12 digital output is compatible with version 1.3 of the protocol and can be connected to the data logger HD32MT.3 or to any other data logger with SDI-12 input.
  • 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 10 m standard length, with open wires at the end.
