Metroglas dissolved oxygen sensors provide reliable results over a broad measurement range—from 100 ppm up to 100% oxygen saturation. These low-maintenance electrodes are extremely suitable for applications in the pharmaceutical and biotechnology industries.
The inline amperometric dO2 sensor is created to high hygienic standards and withstands both clean-in-place (CIP) and sterilize-in-place (SIP) procedures. The PTFE-reinforced silicone membrane is easy to replace, ensuring stable performance over the complete lifetime of the electrode with minimized downtimes when the membrane must be exchanged.
Designed mainly for situations like monitoring cell cultures, these inline amperometric dO2 sensors can also be used for various other applications, e.g., drinking water, wastewater, fermentation broths, beer, wine, and fruit juice production, and more.
