1. Product: Ultra-low concentration UV Flue Gas Analyzer

2. Model: ZP-690-2

3. Product Introduction:

Based on the ultraviolet differential optical absorption spectroscopy (DOAS), It can fast and reliably measure the ultra-low concentration SO2,NO,NOx, NH3, H2S, CL2, HCL and other gases in flue gas.

4. Working principle: 

The measuring unit of the analyzer is composed of light source, gas chamber, optical fiber and spectrometer (including diaphragm, holographic grating, linear detector) and other components.

The ultraviolet light emitted by the light source enters the gas chamber through the optical window, and is absorbed by the sample gas flowing through the gas chamber. The light carrying the absorption information of the sample gas is converged by the lens and then coupled into the optical fiber, and sent to the spectrometer through the optical fiber for spectroscopy. After processing, the absorption spectrum of the gas can be obtained.

·Adopting multiple fold-back technology, the effective optical path exceeds 1 meter

·Resolution is less than 1mg/m3 for real ultra-low measurement

·Measure NO & NO2, no need of Nox converter
