Ordering Information

FermProbe® electrode housings are designed to be used with Model F-615, F-607 and F-600 style FermProbe pH electrodes. These housings fit nearly all standard 25 mm side ports found in production and pilot plant vessels and are available in a variety of different lengths to suit your application.

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.

SPECIFICATIONS

• 316L stainless steel construction.
• Serialized for traceability to mill steel specifications.
• RA32 finish with electropolish on all wetted parts.
• Permanently secured port retainer ring for additional operator safety.

Additional Features Include:

• Guarded versions for rugged handling while protecting the pH glass bulb in a production environment.
• Unguarded versions for viscous media.
• Available in a variety of lengths for different insertion length requirements.
• Custom designs and modifications promptly quoted.

How to Order a Housing

(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 how far the housing and electrode should extend for best performance (see illustration above). For most process media the minimum length is optimum. However, if the media is viscous and tends to thickly coat the inner vessel wall, then a longer length that protrudes farther into the vessel may provide better pH electrode performance.

(4) Choose a pH electrode from among the FermProbe models F-615, F-607 and F-600. 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.
