Fluoroprobe

EFL-3 Luminescent/optical Dissolved Oxygen Analyzer

For WASTEWATER and AQUACULTURE applications
No electrolyte solutions, membranes, sensor caps or cartridges to change.
No more constant calibration or probe fouling.
NO FLOW NECCESSARY
Optical measurement does not consume oxygen, therefore the problems associated with the consumption of oxygen will be drastically reduced or eliminated.
There are no parts to replace on the probe.This reduces the hours of lost time for probe maintenance and eliminates the cost of probe replacement parts.
Covered by five international Patents from countries around the world.
