What is Fluorescence?
The ability to absorb light at one wavelength (blue) and then to emit it at another (red).
How could oxygen be measured by this?
Our patented sensor, which is made of silicone rubber, has an added property which in the presence of oxygen effects the amounts of light which is emitted in the red region.
Why would another oxygen measurement method be needed in the market place?
Existing oxygen methods are the Clark Probe or Galvanic type. Probes based on these methods require constant attention due to the fact that an electrochemical reaction is taken place under water behind a teflon membrane which allows not only oxygen but all other gases and some ions to be involved in the electrochemical reaction.
What are the advantages of Fluorescence over Clark and Galvanic probes?
1. Measurement of oxygen is optical with the rubber in contact with the water only.
2. Clark and Galvanic probes require flow across the probe. The Fluoroprobetm does not.
3. Clark and Galvanic probes consume oxygen and any water borne organisms that also consumes oxygen, and coats the membrane causes rapid O2 depletion behind the membrane. Fluoroprobetm, when coated with Bio-Mass can simply be wiped off and immediately returned to service with NO need for recalibration.
