The sensor measures hydrogen partial pressure through diffusion across a silicone membrane to a polarized platinum anode, generating a current proportional to hydrogen concentration. The result is reliable hydrogen measurement with detection limits down to <50 nM.

You will get a fast-responding sensor for reliable hydrogen measurements in liquid and gas. You can choose between the standard H₂ sensor and the H₂-X version with built-in H₂S protection for environments containing hydrogen sulfide.
