What is claimed is: 1. An apparatus comprising: an oxygen depletion sensor (ODS) comprising: a thermocouple; a first nozzle configured to direct heat from combustion of a first gas, liquid, or combination thereof to the thermocouple; a second nozzle configured to direct heat from combustion of a second gas, liquid, or combination thereof to the thermocouple; and a first igniter. 2. The apparatus of claim 1, wherein the first nozzle comprises a first air inlet aperture and the second nozzle comprises a second air inlet aperture larger than the first air inlet aperture. 3. The apparatus of claim 1, wherein a first injector introduces the first gas, liquid, or combination thereof into the first nozzle at a first flow rate and a second injector introduces the second gas, liquid, or combination thereof into the second nozzle at a second flow rate different than the first flow rate. 4. The apparatus of claim 1, wherein the first igniter is configured to instigate combustion of the first gas, liquid, or combination thereof or combustion of the second gas, liquid, or combination thereof. 5. The apparatus of claim 1, further comprising a second igniter, wherein the first igniter is configured to instigate combustion of the first gas, liquid, or combination thereof and the second igniter is configured to instigate combustion of the second gas, liquid, or combination thereof. 6. The apparatus of claim 1, wherein the first nozzle and the second nozzle are directed to different sides of the thermocouple. 7. The apparatus of claim 1, wherein the first nozzle is spaced at a greater distance from the thermocouple than is the second nozzle. 8. The apparatus of claim 1, further comprising a frame for positioning the first nozzle and the second nozzle relative to the thermocouple. 9. The apparatus of claim 1, further comprising a first coupler for coupling the apparatus with a first pressurized source of fluid and a second coupler for coupling the apparatus with a second pressurized source of fluid. 10. The apparatus of claim 1, further comprising a fluid flow controller comprising a first valve configured to selectively direct a fluid to the first injector and a second valve configured to selectively direct a fluid to the second injector. 11. The apparatus of claim 1, further comprising a first injector configured to introduce the first gas, liquid, or combination thereof into the first nozzle and a second injector configured to introduce the second gas, liquid, or combination thereof into the second nozzle.
