Self-adhesive optical point SP-PSt3-SA for oxygen sensor PreSens

Description

Thanks to the new self-adhesive technology, the SP-PSt3-SA optical dots can be easily attached to almost any transparent glass or plastic container, making oxygen measurement and control even easier. Then, with the help of an oximeter, oxygen is measured non-contact and non-invasively from the outside - through the vessel wall.

SP-PSt3-SA optical points are extremely versatile and can be applied in a variety of industries, from biotech applications to quality control of packaged or bottled products.

Benefits of non-invasive oxygen measurement with the PreSens optical point

• Simplified integration with new self-adhesive technology
• Online monitoring without sampling
• Non-invasive measurements through the vessel wall
• Compatible with glass and almost all plastic containers
• Pre-calibrated and ready to use
