60 pH
The sensor is a combination electrode. The electrode is made of a proton selective glass which contains both a buffer solution of pH ~7 and a reference electrode of Ag/AgCl. A silver wire coated with AgCl is immersed within the buffer solution. Proton ions on both sides selectively interact with the glass which creates a gradient. The hydrogen ion concentration of the buffer is invariant. The potential difference is determined relative to the reference electrode.
