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.

The leaf wetness degree is a basic information in the agricultural and floriculture fields to determine the most appropriate phytosanitary treatment to prevent mould and fungal infections in general that can affect the plants and crops in the presence of condensation on the leaves.

The double sensitive surface allows to determine the wetness degree both on the top and on the bottom of the leaf, important feature to get accurate indications, being that the two sides of the leaf have different drying times.

In order to ensure a long duration of the sensor, the surface of the sensor is specially treated to resist to the atmospheric agents and to the chemical agents present in pesticide products.

The sensor is already supplied with factory-calibration and does not require any calibration by the user. The output is 0.5 … 3 V analog voltage with a fixed 5 (HD3901.5) or 10 (HD3901.10) m connecting cable. Power supply 5… 18 Vdc.

The temperature probe TP32MTT.03.1 is equipped with six Pt100 1/3 DIN sensors for measuring the temperature at the depth of: +5 cm, 0, -5 cm, -10 cm, -20 cm, -50 cm with respect to the ground level.

The fibreglass tube ensures a perfect impermeability and a high thermal isolation along the terminal axis.

Digital RS485 output with MODBUS-RTU protocol.

8-pole M12 male connector.

6…30 Vdc power supply.

It can be connected to the RS485 port of the HD32MT.1 or the HD32MT.3 data logger.
