Easy Integration into Transparent Vessels for Online Oxygen Monitoring
Self-adhesive Oxygen Sensor Spot SP-PSt3-SA
With the new self-adhesive technology it is easy to integrate these sensor spots in nearly any transparent glass or plastic vessel. The oxygen is measured contactless and non-destructively from the outside – through the vessel wall. The SP-PSt3-SA has a measurement range of 0 – 100 % oxygen in dissolved or gaseous phase and can therefore be used for measurements in liquids as well as in headspace. These sensor spots are extremely versatile and can be applied from biotechnological applications up to quality checks for packed or bottled products.
- Simplified integration with new self-adhesive technology
- Compatible with glass & nearly all plastic vessels
- Pre-calibrated & ready-to-use
- Online monitoring without sampling
- Non-invasive measurements through the vessel wall
