5.5 Installing the pH/ORP Electrode
Note: Improve stability in
high purity water by
grounding the solution
near the electrode.
Different mounting equipment is available for the three configurations for mounting the
electrode. The electrode can be configured as an in-line unit installed in a full pipeline (see
Figure 15) or on the end of a dip tube as a submersible unit in a tank or other vessel. The
electrode also can be placed in a flow-thru cell for applications of flow with very little
pressure (see Figure 16). Maximum pressure is 35 psi for in-line installation or 40 feet of
immersion depth for submersible installation. Do not deviate orientation more than
90 degrees from vertical for the three types of installation. The configuration used
determines whether the bushing or collar is threaded with the reference tube and cable
prior to installation. Maximum temperature for the electrode is 60 °C.
