Patent ID: 8608926

Claim:
A sensing probe, configured to measure the content of an oxygen reducible substance in a fluid, comprising: a probe body containing an interface and processing circuit, a dry sensing head comprising an amperometric sensor configured to measure the content of said oxygen reducible substance, wherein said dry sensing head is removable from said probe body, said dry sensing head and said probe body comprising respective coupling means cooperating with each other and configured to be separable to allow removing of said dry sensing head from said probe body, wherein said sensing probe further comprises connecting elements configured to connect in a removable manner said removable dry sensing head to the interface and processing circuit of said probe body, and wherein the removable dry sensing head further comprises a cap and a printed circuit board (PCB) fixedly attached to the cap, said printed circuit board (PCB) being mounted transversally with respect to said sensing probe, the amperometric sensor being mounted on the printed circuit board (PCB), on a face opposed to the probe body.
