Online UV NOx Analyzer
EDK7200
Overview
Overview
ETG's EDK7200 UV absorption spectroscopy NOx online gasanalyzer, which measures NO, NO2 and total nitrogen oxides NOx in the atmosphere, Beer-Lambert's law based on UVabsorption spectrum, UV light at 405 nm wavelength. When passing through the NO2 gas sample chamber, it is absorbed by NO2.The absorption value and NO2 concentration follow Lambert Beer's law. By measuring the change value of the ultraviolet light signal before and after absorption, the reference light source is compared and calculated, and the measured value is analyzed. The concentration value of NO2; when measuring NO, the sample gas passes through the NO2 scrubber, and the NO in the sample gas and the ozone O3 are highly reacted 100% to form NO2 for measurement, and the concentration of NO2 before washing and NO2 after washing are measured. The difference in concentration gives the concentration of NO; and the total NOx is the sum of NO and NO2.
