Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
79 words
A device for detecting a medium, comprising means for detection of a substance, an elongated diffusion sensor hose coupled at an end thereof to the detection means, and a reaction material disposed adjacent and along said sensor hose, said material reacting when in contact with the medium to be detected to produce a substance capable of diffusion into said hose and detectable by said detection means, and means for carrying the substance through said hose to said detection means.
Claim 2
Independent Claim
79 words
A device for detecting a medium, comprising means for detection of a substance, an elongated diffusion sensor hose coupled at an end thereof to the detection means, and a reaction material disposed adjacent and along said sensor hose, said material reacting when in contact with the medium to be detected to produce a substance capable of diffusion into said hose and detectable by said detection means, and means for carrying the substance through said hose to said detection means.
