Oxygen sensitive PET bottle cap OSC-PSt3

Description

To measure oxygen penetration into opaque bottles, the PreSens PSt3 optical point must be placed on the transparent oxygen sensitive OSC-PSt3 cap. 

Three seals ensure the cover is gas-tight. A safety screw adapted to the bottle thread is used to fix the cap.

This non-invasive measurement demand is ideal for food and beverage applications.
