Oxygen Microsensors

The non-invasive oxygen sensors measure the partial pressure of both dissolved and gaseous oxygen. These sensor spots are used for glassware and disposables. The sensor spots are fixed on the inner surface of the glass or transparent plastic material and can therefore be measured in a non-invasive and non-destructive manner from outside, through the wall of the vessel. Different coatings for different concentration ranges are available.

• On-line monitoring
• Non-invasive & non-destructive measurement
• Measurement range from 1ppb up to 45 ppm dissolved oxygen
• No consumption of oxygen
• Signal independent on flow velocity
• Measures oxygen in liquids as well as in gas phase
• Autoclavable (SIP: 130 °C/226°F, 2 atm steam sterilization) & CIP (Cleaning in place)
