Ambient air SO2 Analyzer ZR-3340

UV light radiates at shorter wavelengths than visible light and cannot be seen by the human eye. However, when UV light is absorbed by certain materials, it is reflected back as longer wavelength visible radiation, or visible light. This phenomenon is referred to as UV-induced visible fluorescence. So, using the fluorescence characteristics and intensity that occur when certain substance molecules are exposed to light, quantitative analysis can be conducted on the substance.

SO₂ molecules absorb UV light at the wavelength of 200nm~220nm. The absorbed UV energy excites the outer electrons to the next state. The excited electrons then return to the original state and emit photons at the wavelength of 240nm~420nm. Within a certain concentration range, the SO₂ concentration is directly proportional to the fluorescence intensity.

Powerful function and ensure data stable

> Equipped with precision light sources and optical sensors, ensure long service life and effective anti-interference.

> UV-fluorescent detector resistant to moisture interference.

> Uses a built-in inert PTFE sample inlet filter, which do not adsorb or react with the measured gas components.

> Adaptive filtering algorithm, fast response, low detection limit, high sensitivity.

> Built-in hydrocarbon remover effectively removes the impact of polycyclic aromatic hydrocarbons (PAHs) in the air on measurement data.

> Measure environmental temperature, humidity, pressure, and provide real-time compensation for temperature and pressure, suitable for stable and accurate monitoring in different conditions.
