WebApr 28, 2024 · The pH electrode behaviour follows the Nernst equation: E = E0 + 2.303 (RT/nF) log aH+ where slope, also called sensitivity, is denoted by -2.303 RT/nF and pH is equal to -log aH+. Since R, F, and n are constants, the slope changes with temperature and this effect can be compensated by a pH meter with ATC capability. Click image to enlarge. WebAn optical pH sensor basically comprises two essential parts: A pH sensitive sensor layer and a read-out device (pH meter). The pH meter consist of a LED and photodiode which excites the compounds in the pH sensor and detects its luminescence emission.
