AnalysisPortable Dissolved Oxygen
Hand Held with Logger
Model 3100 portable dissolved oxygen analyzer is a state of the art, easy to use meter that provides many benefits to the plant operations staff fluorescence sensor technology ,no membranes, fill solutions, or cartridges,sensor does not have to remain moist data logging with direct downloading to your PC calibration is factory programmed.
The Aysix Portable Dissolved Oxygen Model A6-IIG-3100 is a unique system that combines advanced electronics with a solid-state optical sensor. The sensor utilizes an optical technique that does not consume oxygen like all standard membrane sensors and unlike other optical sensors is not damaged by direct or indirect exposure to sunlight. It is a multi-range analyzer designed for the measurement of dissolved oxygen in all aqueous solutions. The microprocessor based electronics of the analyzer provide a high degree of ﬂexibility and ease of use. Data logging and the ability to download the data directly to a computer are standard features.
A very speciﬁc energy wavelength is transmitted to a ruthenium compound immobilized is a sol-gel matrix. The ruthenium will absorb this energy, changing the outer electron’s energy level. The electron will then collapse back to its original energy state, emitting the energy as a photon with a different speciﬁc wavelength. This is called
ﬂuorescing. If the intensity of the transmitted wavelength is tightly controlled, the amount of ﬂuorescing is both predictable and repeatable. If oxygen molecules are present the amount of ﬂuorescing is reduced, referred to as ﬂuorescence quenching. By measuring the amount of quenching it is possible to determine the amount of oxygen present.
