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 fi eld 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 are factory-calibrated and do not require any further calibration by the end user.
The circuit board is protected inside a housing made of plastic material and sealed with epoxy resin which allows achieving reliable measurements even in harsh environmental conditions.
The 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.
The probes are equipped with a fi xed cable, 5 or 10m standard length, with open wires at the end.
