The “orange cap” probe: from 20 cm to 1.20 m long and from 2 to 8 measurement depths, to read the full water profile of your soil.

The HSTI multi-depth probe — recognisable by its orange cap — is the tool for fine-tuned irrigation management: instead of one figure at one depth, it gives you the complete profile of your soil, depth by depth.

An effective watering round means water that reaches the roots — neither above (evaporated) nor below (drained). With several measurement depths, you watch the wetting front go down in real time: you know whether your 3 hours of irrigation wet 20 cm or 60 cm, and you adjust the run time accordingly. It is the difference between irrigating by habit and irrigating by measurement.
The probes are made by HSTI, a French specialist in capacitive measurement, and integrated by FURGO: self-contained transmission, SIM included, voice alerts and platform included. The hardware is repairable and the data belongs to you — exportable at any time from the Supervisor.
The basic rule: cover the rooting depth plus one depth below it to see the drainage. Established vineyard: 60 cm / 3 depths is the most common choice; market gardening: 40 cm / 2 depths; fruit growing or deep soils: 60 cm and more. If in doubt, describe your plot and we will give you a straight answer.
The single-depth probe measures at one depth only: perfect for triggering a simple alert. The multi-depth probe reads the whole profile: it shows where the water goes, which changes the way you manage your watering rounds.
