Oxygen Optode 4831/4831F
Oxygen Optode 4831/4831F
is a compact fully integrated sensor for measuring the O2 concentration.
Fast Response Foil (4831F, refer overleaf) .
The Aanderaa oxygen optodes are based on the ability of selected substances to act as dynamic fluorescence quenchers. The fluorescent indicator is a special platinum porphyrin complex embedded in a gas permeable foil that is exposed to the surrounding water. For the standard version 4831 a black optical isolation coating protects the complex from sunlight and fluorescent particles in the water. This sensing foil is mounted on a sapphire window providing optical sampling from inside a watertight housing.
