FAQ

FAQ of Best Water Treatment Online Digital Dissolved Oxygen Meter

1. How can dissolved oxygen be measured using fluorescence?
A very specific energy wavelength is transmitted to a ruthenium compound immobilized in 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.

2. How often do the sensors need to be calibrated?
We recommend that the calibration be checked at least once a year. The sensor will drift less than one percent per year.

3. How long has this technology been in use?
Fluorescence technology has been used to measure oxygen uptake in the medical industry for decades. In the early 2000s, the technology was adapted for use in measuring dissolved oxygen in biological reactors. The key issues in making the technology viable in the water treatment industry were the durability of the sensing element and cost. Another important concern was packaging the system in a way that was easy to use and required very little maintenance. The Insite units have accomplished all of these objectives.

4. Can the sensor be calibrated in the field?
Yes, the sensor can be calibrated in the field. A simple calibration to a reference takes about a minute.
