A rebreather apparatus includes at least one pressurized container of oxygen, at least one pressurized container of a diluting gas, and at least one valve to supply the oxygen and diluting gas to a rebreathing loop. The valve is controlled by a signal from at least one oxygen sensor, wherein the oxygen and diluting gas combine to form a breathing gas that is circulated by the rebreathing loop. At least one container of calibrating gas stores the calibrating gas at ambient pressure and temperature. At least one valve is connected to the at least one oxygen sensor presenting the calibrating gas to the oxygen sensor during calibration of the oxygen sensor and presenting the breathing gas to the oxygen sensor at all other times.
