ABSTRACT:
A food cooking oven, particularly for use in commercial or collective food service applications, includes a cooking cavity and a heat generating device. A fan is provided for fan-assisted cooking and is adapted to transfer heat to the inside of the cooking cavity. A zirconium-oxide cell is located at a wall of the oven and has one of its sides open towards the outside atmosphere and the other one of its sides open towards the inside of the cooking cavity and is capable of measuring the relative concentration of oxygen within the cavity. The terminals of the zirconium-oxide cell are connected to an indicator, which is arranged so as to be visible from the outside of said oven. The cell terminals are also connected to a controller, which preferably includes at least one connected electronic microprocessor unit and is arranged so as to be able to automatically determine the moisture content of the gas mixture inside the cooking cavity.
