Model 356 Guarded Housing (Sartorius Safety Port 25 mm – Pg13.5)

When these housings are used with the Sartorius safety port, the port will release internal steam pressure in the vessel before the housing is completely disengaged from the port.

The metric FermProbe pH electrodes thread directly into the 356 housings, eliminating the need for a threaded retainer nut. In order to prevent twisting the cable, the metric FermProbes have a detachable cable.

Guarded and unguarded versions are available. Using a guarded housing is highly recommended for pH electrodes to provide maximum protection against damage to the sensing bulb. However, highly viscous media is prone to clog the guard.

Specification

• 316L stainless steel construction.
• Serialized for traceability to mill steel specifications.
• RA32 finish with electropolish on all wetted parts.
• FDA compliant external EPDM o-rings.
• 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.
• Unguarded versions for viscous media.
• Custom designs and custom modifications promptly quoted.

How to Order a Housing

1. Confirm that the vessel has a Sartorius 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 process applications except when media is highly viscous. Highly viscous media is prone to clog the guard area of the housing.
3. Choose the correct steam sterilizable FermProbe pH electrode.
