F-615 Sterilizable pH Electrode

The T-Pull^® and standard style FermProbe pH electrodes are designed to be used in bioprocess applications where CIP/SIP procedures are used. Built to withstand repeated steam sterilization cycles, the FermProbe quickly stabilizes after steam exposure to be back on-line in half the time of other electrodes. This rugged, low impedance, process pH electrode continues to provide fast and precise pH measurements even after harsh use and prolonged steam exposure.

The FermProbe design specifies that the pH electrode be secured to the housing by a free-spinning threaded retainer nut. This allows the electrode to be installed or removed from the housing without twisting or disconnecting the electrode cable.

T-Pull^® Handle FermProbe pH Electrodes

The T-Pull handle eases installation and removal of the electrode from the sensor housing. The electrode can be easily removed from the housing without being rotated or twisting the cable. This greatly reduces cable fatigue.

Features

• Rugged handle design eases removal of electrode from housing. No tools required.
• Greatly reduces cable fatigue.
• Electrode retainer nut is part of the handle. Cannot be lost or misplaced.
• Available with disconnect cap or integral cable.

Choose Electrode Length

If you have already chosen a sensor housing, select an electrode length with the same Class designation as the housing. The housing ordering information box also lists the correct electrode length to order. If you have not already chosen the housing, please review the recommendations next to each electrode model below.

Confirm Cable Length and Connector

Model F-615 sterilizable pH electrodes require a disconnect cable and connector assembly (see the Accessories tab for information about compatible cables). If you need a different cable length or connector, please call the Sales Department for more information.
