The Model 320 Unguarded Housing is designed to be used with model F-615, F-607, F-600 and F-815 style FermProbe pH electrodes with viscous media. 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. For the guarded equivalent please see Model 330 guarded housing for 25mm side ports.

model 320The 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-607, F-815 and F-600 style FermProbe pH electrodes found on our website.

Specification

  • 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

  • Guarded versions for rugged handling while protecting the pH glass bulb in a production environment (Model 330)
  • Unguarded versions for viscous media (Model 320).
  • Available in a variety of lengths for different insertion length requirements.
  • Custom designs and modifications promptly quoted.
Housing Model Class Typical Vessel Insertion Length Used With pH Electrode Models Used With Electrode Length Housing Part Number
Model 320 A 37 mm ( 1.5″) F-615, F-607 and F-600 130 mm 320-61-H070
Model 320 B 66 mm ( 2.6″) F-615, F-607 and F-600 160 mm 320-61-H100
Model 320 C 113 mm ( 4.5″) F-615, F-607 and F-600 210 mm 320-61-H150
  1. Confirm the vessel has a standard 25 mm side port (for assistance with this please see our FAQ for ‘How do I choose a housing style‘.
  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. If the application will permit the use of a bulb guard then please see Model 330 Guarded Housing instead.
  3. Determine how far the housing and electrode should extend for best performance. 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, F-600 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.
