F-815 Sterilizable pH Sensor

The new F-815 offers the same form, fit and function as the F-615 with improved performance and USP Class VI materials. The unique construction methods used by Broadley-James allows this pH sensor to exhibit virtually zero drift after steam sterilisation (SIP).

The T-Pull® style FermProbe® sterilizable pH sensor is 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 sensors.

This sensor design specifies that the sterilizable pH sensor be secured to the housing by a free-spinning threaded retainer nut. This allows the sensor to be installed or
removed from the housing without twisting or disconnecting the sensor cable. Additionally, the T-Pull handle eases installation and removal of the sensor from the sensor housing.

The Model F815 FermProbe has two built-in electrolyte chambers that act to protect and isolate the sensitive inner AgCl reference half-cell. This “double junction”, dual-chamber design effectively prevents the most common failure modes of pH sensors in biopharmaceutical applications.

T-Pull® Handle FermProbe Sterilizable pH sensors

The T-Pull handle eases installation and removal of the sensor from the housing. The sterilizable pH sensor 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 sensor from housing. No tools required.
  • Greatly reduces cable fatigue.
  • Sensor retainer nut is part of the handle. Cannot be lost or misplaced.

Sensor Housings

The F-815 pH sensor has a metric Pg13.5 threaded polymer cap allowing it to be used with European style housings. We recommend the following Broadley-James sensor housings for use with the FermProbe F-815 sterilizable pH sensor:

Compatible Cables

The T-Pull style F-815 pH Sensor uses a standard S8 detachable cable connection. We recommend the following cables for use with it:

Cable Type Sensor Connector & Device Connector Device Terminal
HP Plug to BNC Plug, Type A s8 cable bnc small bnc-jack
HP Plug to BNC Plug, Type M s8_cable-bnc-m-small bnc-jack
HP Plug to DIN Plug, Type M s8_cable-din-small DIN-jack
 HP Plug to Crimped Ferrules, Type M  s8_cable-ferrules-m-small  terminal-block
 HP Plug to Ferrules, Solution Ground, Type N
 s8_cable-ferrules-n-small  terminal-block

 

Choose Sensor Length

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

Confirm Cable Length and Connector

Model F-815 pH sensors require a disconnect cable and connector assembly (see Accessories tab for information about compatible cables).
