Gf ph probe maintenance
WebpH sensor troubleshooting is the key to successful pH analysis. Since the pH sensor is the only part of the analytical instrument that is in direct contact with the sample, its selection … WebThe 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.
