In 1986 Broadley-James introduced the first steam-sterilizable, gel-filled and sealed pH sensor. The pH FermProbe® met wide acceptance in the biotechnology and pharmaceutical industries for use in fermentation processes. In 1993 Broadley-James introduced the OxyProbe® dissolved oxygen sensor, providing a complete solution for measurement and control in both cell culture and fermentation processes. Providing Industrial Tools for Industrial Science, Broadley-James continues to advance the state of the art in measurement, automation and control. We also distribute a range of innovative products from our partners, for both Upstream and Downstream bioprocessing.

pH dissolved oxygen accessories


The primary components of a measurement loop are the sensors and transmitters. However, when readings are suspect or if noise and interference are a problem, it can be hard to find the source of the problem without having the proper equipment. Many of the BioProcess accessories are designed with troubleshooting in mind, allowing the metrology department or even the operator to diagnose equipment quickly and efficiently.
