Description
Description
Optical points PreSens SP-PSt7-NAU and SP-PSt7-YAU can be built into any transparent or semitransparent container or optical window, while measurements are performed non-invasively from the outside - through the container wall. Due to their small size, these sensors are the most versatile and can be used in many applications to measure dissolved and gaseous O2. For example, in the development of bioprocesses (monitoring oxygen in shake flasks), measuring photosynthesis and cellular respiration of various organisms, bacteria, cell cultures, yeast or fungi.
These oxygen sensor points have a measuring range of 0 to 100% O2 with a detection limit of 0.03% O2.
SP-PSt7-NAU - is not autoclavable.
SP-PSt7-YAU - autoclavable.
