BJC Model 320 Housing 25mmThe 320 style unguarded electrode housing is designed to be used with the Model F-615 style FermProbe® pH electrode. This housing fits nearly all standard 25 mm side ports found in production and pilot plant vessels and is available in a variety of different lengths to suit your application. The Model 320 unguarded housing is preferable for use in viscous media. The Model 330 Guarded housing is the first-choice equivalent if high viscosity clogging the guard is not a concern.

The FermProbe design requires that the pH electrode be secured to the housing by a free-spinning threaded retainer nut. This allows the electrode to be installed into or removed from the housing without twisting or disconnecting the electrode cable. This feature is very helpful when calibrating the pH electrode tank side in a production environment.

This housing is also designed to be used with Model F-815 FermProbe pH electrodes found on our website.

  • Custom designs and modifications promptly quoted.
  1. Confirm the vessel has a standard 25 mm side port.
  2. Determine whether the application will permit the use of a bulb guard on the housing. The bulb guard design is highly recommended for all types of applications except where media is highly viscous. Highly viscous media is prone to clog the guard area of the housing which can cause erroneous measurements.
  3. Determine whether the application will permit the use of a bulb guard on the housing. The bulb guard design is highly recommended for all types of applications except where media is highly viscous. Highly viscous media is prone to clog the guard area of the housing which can cause erroneous measurements. If the application will permit the use of a bulb guard then please see Model 330 Guarded Housing instead.
  4. Choose a pH electrode from among the FermProbe models F-615 and F-815. Each of these rugged process pH electrodes secure to the housing with a free-spinning threaded retainer nut. The pH electrodes must be ordered separately.
