InsiteIG Model 1000 Dissolved Oxygen analyzer

No damage by direct or indirect exposure to sunlight 

The Insite Instrumentation Group Model 1000 dissolved oxygen analyzer is a unique system that combines advanced electronics with a solid-state, optical sensor. No other dissolved oxygen system can compare with the features and benefits of this revolutionary design. The sensor utilizes and optical technique that does not consume oxygen like all standard membrane sensors.

• No weekly or monthly sensor cleaning
• Works in low flow / no flow applications
• Extremely accurate in anoxic zones
• Automatic error detection
• Analyzer self test
• Simple user interface
• Simple start-up

A very specific energy wavelength is transmitted to a ruthenium (RU) compound immobilized in a sol-gel matrix. The ruthenium will absorb this energy, changing the outer energy 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 fluorescence. If the intensity of the transmitted wavelength is tightly controlled, the amount of fluorescence 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.
