<p>The device has a simulator unit with an absorbing body (82) in which a sliding canopy (108) allows only a preset water quantity to enter into the body. A reclinable cup (74) of the unit is inclined around its axis to adjust simulations of permeability, capillarity and water retaining capacity performed by the unit. A thermostat unit (88) blocks a return of a lever arm when an intensity of solar radiation exceeds a preset threshold. The lever arm has an annular magnet (80) whose vertical movement causes a movement of a bistable ferromagnetic core (48) which moves to a low position when a force subjected by the core (48) is less than a compression force of a spring in order to close an orifice (39) of a channel (38). The core (48) moves to a high position when the force subjected by the core (48) is greater than the compression force in order to unblock the orifice.</p> |
