Claims
- 1. A method of measuring the presence and the amount of carbon monoxide present in gases comprising
- exposing a body consisting of silver oxide to said gases, and
- measuring the change of electrical conductivity of said body of silver oxide in response to carbon monoxide in said gases.
- 2. A method as recited in claim 1 wherein said body consisting of silver oxide is a pellet of compressed silver oxide granules.
- 3. A method as recited in claim 1 wherein said body consisting of silver oxide is a film of silver oxide deposited on a substrate.
- 4. A method of measuring the presence and the amount of cabon monoxide present in gases comprising
- immersing a body consisting of silver oxide in gases containing carbon monoxide,
- applying a voltage across a predetermined part of said silver oxide body,
- measuring the change in current flowing across said predetermined part of said silver oxide body caused by the carbon monoxide present in said gases, and
- displaying said change of current flowing as an indication of the amount of cabon monoxide present.
- 5. The method as recited in claim 4 wherein said body consists of a compressed pellet of silver oxide granules.
- 6. The method as recited in claim 4 wherein said body consists of a film of silver oxide deposited on a substrate.
- 7. The method as recited in claim 4 wherein said body consisting of silver oxide is doped with a high valence metal oxide selected from a group consisting of manganese oxide and cobaltic oxide.
- 8. A method of measuring the presence and amount of carbon monoxide present in gases comprising
- heating a pellet consisting of of silver oxide granules for from 5 to 10 minutes in the atmosphere at a temperature on the order of 275.degree.C,
- cooling said pellet to the ambient temperature,
- immersing said pellet in said gases, and
- measuring the change of electrical conductivity of said pellet caused by the carbon monoxide in said gases.
- 9. A method of measuring the presence and amount of carbon monoxide present in gases comprising
- exposing a pellet of compressed granules consisting of silver oxide doped with a high valence metal oxide selected from a group consisting of manganese oxide and cobaltic oxide, and
- measuring the change of electrical conductivity of said pellet in response to carbon monoxide in said gases.
