Hygienic optical sensor measures dissolved oxygen

Endress+Hauser

Endress+Hauser

The Memosens COS81D hygienic optical sensor (photo) measures dissolved oxygen in fermenters and bioreactors that are used in the food, pharmaceutical and biotechnology industries, and in drinking water and boiler-feedwater applications, as well. It can be used in all measuring points, from laboratory fermenters to production processes. This device measures dissolved oxygen, gaseous oxygen and temperature, with an accuracy to±0.2%, says the company. It works in process temperatures from 15 to 280°F, and pressures from 0 to 190 psi. The compact stainless-steel sensor meets EHEDG (Type EL Class 1) and ASME BPE (including USP Class VI and FDA conformity) hygienic requirements to avoid product contamination. It also meets the requirements of GMP and GLP, and is designed to withstand clean-in-place and steam-in-place procedures, according to the manufacturer. — Endress+Hauser, Greenwood Ind.
