A miniature inexpensive, oxygen sensing element

This paper is a progress report by: Ceramphysics, Inc. on the design, fabrication and testing of a miniature, inexpensive, oxygen sensing element. Four tasks are discussed. The first is the choice of ceramics, development of a sealing technique and the design of a heating element; the second is preliminary fabrication; the third the testing of prototypes and final fabrication; and the fourth is the preparation of the final report.
