Abstract:
A low-slope pH electrode (100) is provided according to an embodiment of the invention. The low-slope pH electrode (100) includes an electrode body (102), a pH-sensitive glass (122) fused into the electrode body (102), with the pH-sensitive glass (122) including a predetermined area, and a mask (124) formed over a predetermined portion of the predetermined area of the pH-sensitive glass (122) in order to form a low-slope pH characteristic. At least a portion of an ion exchange performed by the pH-sensitive glass (122) is blocked by the mask (124).
